What is the output of type([1, 2, 3]) in Python?
In Python, square brackets [] denote a list literal, so [1, 2, 3] is an instance of list. The type() function returns the class type of an object. Therefore, type([1, 2, 3]) yields . Python docs for type()
Which keyword is used to define a function in Python?
def
function
fun
lambda
The def keyword is used to define named functions in Python. While lambda creates anonymous functions, def gives a function name and body. This is the standard syntax for user-defined functions. Defining functions in Python tutorial
Which operator is used for exponentiation in Python?
**
^
%
*
In Python, ** denotes exponentiation, so 2**3 equals 8. The caret (^) is bitwise XOR, not power. Modulo (%) and multiplication (*) serve different purposes. Operator precedence documentation
Which of these data types is immutable in Python?
tuple
list
dict
set
A tuple is immutable, meaning its contents cannot be changed after creation. Lists, dictionaries, and sets are mutable and allow item assignment or modification. Using immutable types can be beneficial for ensuring data integrity. Tuples and sequences documentation
How do you denote a single-line comment in Python?
#
//
/* */
Python uses the hash symbol (#) for single-line comments. Everything after # on that line is ignored by the interpreter. Languages like C use /* */, and HTML uses for comments. Python comments in the tutorial
Which of these is a boolean literal in Python?
True
true
1
"True"
Python boolean literals are capitalized: True and False. Lowercase true or false are not recognized. Numeric 1 is truthy but not a boolean literal. Boolean operations documentation
What operation does the // operator perform in Python?
Floor division
True division
Modulo
Exponentiation
The // operator performs floor division, returning the quotient rounded down to the nearest integer. True division uses a single slash (/). Modulo (%) returns the remainder, and exponentiation is **. Arithmetic operations reference
Which of the following is a valid Python variable name?
_var1
1var
var-name
var name
Variable names must start with a letter or underscore, followed by letters, digits, or underscores. Names like 1var start with a digit and are invalid. Hyphens and spaces are not allowed. Identifier rules in Python reference
How do you get the number of items in a list `my_list`?
len(my_list)
size(my_list)
count(my_list)
length(my_list)
The built-in len() function returns the number of items in a list. There is no size() or length() function, and count() counts occurrences of a specific value. len() function documentation
Which keyword begins a block of code that catches exceptions?
except
try
finally
catch
In Python, the except keyword is used to catch and handle exceptions following a try block. The try keyword starts the block that may raise exceptions. There is no catch keyword in Python. Handling exceptions in Python tutorial
What is the default return value of a Python function that has no return statement?
None
0
""
[]
If a Python function does not explicitly return a value, it returns None by default. This is a special singleton object. It is not equivalent to 0 or an empty string or list. Return statement reference
Which loop repeats as long as a condition remains true?
while
for
do-while
until
The while loop continues to execute its block as long as the given condition is true. Python does not have do-while or until loops. A for loop iterates over a sequence. While loops documentation
Which of these data types is mutable in Python?
list
tuple
str
int
Lists are mutable and allow in-place modification of elements. Tuples, strings, and integers are immutable—they cannot be changed after creation. Data structures tutorial
How would you import the built-in math module?
import math
include math
using math
require math
Python uses the import statement to bring in modules. import math loads the math module for use. include, using, and require are not valid Python import syntaxes. Importing modules tutorial
What symbol indicates the start of a code block after statements like if or for?
:
;
{
indentation
A colon (:) at the end of statements like if, for, or def indicates that an indented block follows. Semicolons and braces are not used for blocks in Python. Indentation is required but not a symbol. Indentation reference
Which comparison operator checks for equality in Python?
==
=
===
!=
The double equals (==) operator tests whether two values are equal. A single equals (=) is used for assignment. !== and === are not valid operators in Python. Comparisons reference
What does the list comprehension [x for x in range(5)] produce?
[0, 1, 2, 3, 4]
(0, 1, 2, 3, 4)
{0, 1, 2, 3, 4}
'01234'
A list comprehension with range(5) yields a list of integers from 0 to 4. The syntax [x for x in range(5)] explicitly creates a new list. Parentheses create tuples, braces create sets, and quotes create strings. List comprehensions documentation
How do you open a file for writing in Python?
open('file.txt', 'w')
open('file.txt', 'r')
open('file.txt', 'rw')
open('file.txt', 'x')
The mode 'w' opens a file for writing and truncates existing content. 'r' opens for reading, 'x' for exclusive creation, and 'rw' is not a valid mode. open() function documentation
Which list method adds an item to the end?
append()
add()
push()
insert()
append() adds a single element to the end of the list. insert() can place an item at any index, while add() and push() are not list methods in Python. List methods tutorial
What is the result of ' '.join(['a', 'b'])?
a b
ab
a,b
['a','b']
The join() method concatenates list elements using the string as a separator. Here, a single space ' ' separates 'a' and 'b'. It does not insert commas or ignore the separator. str.join() documentation
How do you catch multiple exception types in one except block?
except (TypeError, ValueError):
except TypeError, ValueError:
except TypeError | ValueError:
except TypeError & ValueError:
You can catch multiple exceptions by specifying a tuple of exception types in parentheses after except. The other syntaxes are invalid in modern Python. Handling multiple exceptions
What is a lambda function in Python?
An anonymous inline function
A named function
A class constructor
A type of loop
Lambda functions are small anonymous functions defined with the lambda keyword. They can take any number of arguments but only have a single expression. They are often used for short, throwaway functions. Lambda expressions reference
Which syntax represents a set literal?
{1, 2, 3}
[1, 2, 3]
(1, 2, 3)
<1, 2, 3>
Curly braces with comma-separated values define a set. Square brackets define lists and parentheses define tuples. Angle brackets have no literal meaning for collections. Set types documentation
Which placeholder syntax is used by str.format()?
{}
%s
{0}
${}
Empty curly braces {} are replaced by arguments in order when using str.format(). {0} also works for positional indexing, but {} is the basic placeholder. %s is old-style formatting. str.format() documentation
What is the difference between 'is' and '==' operators?
'is' checks identity, '==' checks equality
'is' checks equality, '==' checks identity
Both check equality
Both check identity
The 'is' operator checks whether two references point to the same object in memory. The '==' operator checks if the values of the objects are equal. They serve different purposes. Identity comparisons documentation
Which module provides support for regular expressions?
re
regex
parse
regexp
The re module in the Python standard library implements regular expression operations. There is no built-in regex or regexp module. re module documentation
Which syntax creates a dictionary comprehension?
{k: v for k, v in iterable}
[k: v for k, v in iterable]
(k, v for k, v in iterable)
{k, v for k, v in iterable}
Dictionary comprehensions use curly braces with key: value pairs. List comprehensions use square brackets and set comprehensions use curly braces without colons. Dictionaries tutorial
How do you sort a list in descending order?
sorted(my_list, reverse=True)
sorted(my_list, True)
my_list.sort(desc)
sorted(my_list, asc=False)
The sorted() function takes a reverse parameter to sort in descending order. The other syntaxes are invalid. You can also call my_list.sort(reverse=True). sorted() documentation
What does a generator expression look like?
(x*2 for x in range(10))
[x*2 for x in range(10)]
{x*2 for x in range(10)}
Generator expressions use parentheses to create an iterator that computes values on demand. Lists use square brackets and set comprehensions use curly braces. Generator expressions reference
What does the enumerate() function return when applied to a list?
An iterator of pairs (index, value)
A list of values
A list of indexes
A dictionary mapping indexes to values
enumerate() yields tuples containing the index and corresponding value from the original iterable. It does not return a list or dictionary by itself. enumerate() documentation
What does zip([1, 2], [3, 4]) produce?
An iterator of tuples [(1, 3), (2, 4)]
[1, 3, 2, 4]
{1:3, 2:4}
[(1, 2), (3, 4)]
zip() pairs elements from each iterable into tuples, returning an iterator. Converting to list shows [(1, 3), (2, 4)]. It does not produce a dictionary or flatten the elements. zip() documentation
What is the purpose of the global keyword in Python?
To refer to module-level variables inside a function
To declare a private variable
To optimize performance
To import global packages
The global keyword lets you modify or reference a variable defined at the module level from within a function. Without it, assignments create a new local variable. It is not related to privacy or performance. global statement reference
What is a decorator in Python?
A callable that modifies or enhances other functions
A special kind of loop
A syntax for variable declaration
A built-in ORM tool
Decorators are functions that take other functions as arguments and return a new function with added behavior. They are applied using the @ syntax above function definitions. This allows code reuse and separation of concerns. Decorator glossary entry
How do you create a generator function?
By using the yield keyword inside a function
By returning a list
By defining __iter__
By using async def
A generator function uses yield to produce a sequence of values lazily, pausing its state between yields. Returning a list produces all values immediately. async def defines coroutines, not generators. yield expression reference
What is the Global Interpreter Lock (GIL) in CPython?
A mutex that prevents multiple native threads from executing Python bytecode at once
A lock on global variables
A security feature
A garbage collection mechanism
The GIL ensures that only one thread executes Python bytecode at a time in CPython, simplifying memory management. It is not related to security or garbage collection directly. GIL glossary entry
What is the difference between shallow copy and deep copy?
Shallow copy duplicates top-level objects; deep copy duplicates nested objects recursively
Shallow copy is slower than deep copy
Deep copy only works for lists
They are the same in Python
A shallow copy creates a new container but inserts references to the same items. A deep copy recursively copies all nested objects. Python’s copy module provides both functions. copy module documentation
What does @staticmethod do inside a class?
Defines a method that does not receive an implicit first argument
Defines a method that receives the instance as first argument
Defines a method that receives the class as first argument
Aliases a function from another module
A staticmethod does not take self or cls automatically. It behaves like a regular function but lives in the class’s namespace. classmethod passes the class as the first argument. staticmethod documentation
How do __str__ and __repr__ methods differ?
__str__ is for human-readable output; __repr__ is for unambiguous representation
__str__ is called by repr(); __repr__ by str()
They are interchangeable
__repr__ returns HTML; __str__ returns plain text
__repr__ should return an unambiguous string often used for debugging, and __str__ returns a readable format for end users. str() calls __str__, and repr() calls __repr__. Data model reference
What is a metaclass in Python?
The class of a class, defining how a class behaves
A method decorator
An abstract base class
A memory management tool
Metaclasses are ‘classes of classes’ that determine how classes are constructed. By customizing a metaclass, you can modify class creation. The default metaclass is type. Metaclasses documentation
Which method is called when an attribute is not found the usual ways?
__getattr__
__getattribute__
__setattr__
__getitem__
__getattr__ is invoked only if the attribute wasn’t found normally. __getattribute__ is called for all attribute accesses. __setattr__ handles assignments, and __getitem__ is for indexing. __getattr__ reference
Which module provides the Abstract Base Class (ABC) infrastructure?
abc
types
inspect
abstract
The abc module introduces the ABC class and decorators for defining abstract base classes. It allows you to define methods that must be implemented by subclasses. abc module documentation
How do you implement a context manager in a custom class?
Define __enter__ and __exit__ methods
Define __init__ and __del__
Inherit from threading.Context
Use a decorator only
To make an object usable with the with statement, you must implement the __enter__ and __exit__ methods. __init__ and __del__ are not enough. Context manager reference
What is the difference between classmethod and staticmethod?
classmethod receives the class as first argument; staticmethod does not
staticmethod receives instance; classmethod does not
They are identical
One is Python 2 only
classmethod methods receive the class (cls) as the first parameter, enabling access to class attributes. staticmethod behaves like a regular function without automatic cls or self. classmethod documentation
What does calling super() without arguments do inside a method?
Returns a proxy for the parent class bound to the current instance
Raises a NameError
Calls __init__ of object
Imports the superclass
super() without arguments automatically infers the class and instance and returns a proxy to delegate method calls to the parent class. This simplifies cooperative multiple inheritance. super() documentation
Why might tuples use less memory than lists?
Tuples are immutable and have a smaller memory footprint
Lists use linked lists internally
Tuples are stored on disk
Lists are compressed
Tuples are immutable, so their storage can be optimized with a fixed-size structure. Lists maintain extra space to allow dynamic resizing. This makes tuples lighter in memory. Memory usage tutorial
What is monkey patching in Python?
Dynamically modifying or extending code at runtime
Creating threads manually
Using patches in unittest
Applying security updates
Monkey patching refers to altering or extending classes or modules at runtime without modifying the original source. It can be powerful but risky. Monkey patching glossary entry
What is the difference between iter() and next() when working with iterators?
iter() returns an iterator object; next() retrieves the next value
next() creates an iterator; iter() retrieves values
They are aliases
iter() only works on lists
Calling iter() on an iterable yields an iterator. Calling next() on that iterator returns the next item. Without next(), values are not advanced. iter() and next() documentation
What does pickling refer to in Python?
Serializing and deserializing Python objects
Encrypting data
Compiling code
Logging events
Pickling is the process of converting Python objects into a byte stream for storage or transmission, and unpickling does the reverse. It’s provided by the pickle module. pickle module documentation
What is the descriptor protocol in Python?
Objects with __get__, __set__, or __delete__ methods that manage attribute access
A memory allocation strategy
An interface for file I/O
A threading synchronization tool
Descriptors are classes that define any of __get__, __set__, or __delete__ to control attribute access on other objects. They are widely used for properties and method binding. Descriptor how-to guide
What does MRO stand for and how is it determined in Python classes?
Method Resolution Order determined by C3 linearization
Mutable Reference Object determined by hash order
Meta Class Rule determined by inheritance depth
Module Registration Order determined by import order
MRO (Method Resolution Order) is the order in which base classes are searched when looking for a method, determined by the C3 linearization algorithm. This ensures a consistent and predictable lookup. C3 linearization explanation
How does the async/await syntax work in Python?
Defines coroutines that can pause and resume execution with await
Creates new OS threads for concurrency
Compiles code to machine language
Replaces decorators
async def defines a coroutine function, and await pauses its execution until the awaited awaitable completes. This allows cooperative multitasking without threads. asyncio coroutines documentation
What are coroutines and how are they used in asyncio?
Functions defined with async that can be suspended with await for non-blocking I/O
Threads managed by asyncio
Synchronous generators
Callbacks only
Coroutines are special functions defined with async that yield control at await points, enabling non-blocking execution. asyncio runs these coroutines in an event loop. asyncio library documentation
How do you create a custom metaclass in Python?
Define a class inheriting from type and override __new__ or __init__
Use @metaclass decorator only
Inherit from abc.ABCMeta without changes
Use importlib to load classes dynamically
To define a metaclass, subclass type and override methods like __new__ or __init__ to customize class creation. Then specify it in class definition using metaclass=YourMeta. Metaclasses reference

Cheat Sheet

  1. Essential Python Keywords -

    Understanding Python's 35+ reserved keywords (like def, class, and lambda) is crucial for any python programming quiz. Use a mnemonic such as "DRIED CLASSP" (def, return, if, else, import, del, class, lambda, and pass) to recall common ones quickly. Refer to the official Python docs (python.org) for the full list.

  2. Operator Precedence and Usage -

    Master arithmetic, comparison, logical, and bitwise operators to avoid pitfalls in expressions during a python quiz for beginners or an advanced python quiz. Remember the PEMDAS rule (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) to track evaluation order. Check resources like MIT's lecture notes for detailed precedence tables.

  3. Data Structures: Lists, Tuples, and Dicts -

    Review mutable vs. immutable types by comparing lists ([1,2,3]), tuples ((1,2,3)), and dictionaries ({'a':1}). Try list comprehensions - e.g., [x**2 for x in range(5)] - to sharpen problem-solving for your python programming challenge. The University of Michigan's Python course offers great examples on efficient data structure use.

  4. Functions and Scope Rules -

    Dive into defining functions with default and keyword arguments, and grasp local vs. global scope to ace questions in a test python skills round. Practice lambda expressions: square = lambda x: x*x, and note closures for advanced python quiz sections. Official docs on functions and scopes provide clear guidelines.

  5. Error Handling with try/except -

    Equip yourself with structured exception handling - using try, except, finally, and raising custom errors - so you can gracefully debug code during a python programming quiz. Leverage the logging module for real-time insights and practice with ValueError or TypeError scenarios. Real-world applications are covered in Python's PEP 341 and tutorials from reputable dev portals.
