What is the correct syntax to display 'Hello, World' in Python?
printf('Hello, World')
echo 'Hello, World'
print('Hello, World')
console.log('Hello, World')
The print() function in Python outputs text to the console. The other options refer to commands from different programming languages.
Which of the following Python data types is mutable?
Tuple
Integer
String
List
Lists in Python are mutable, meaning their elements can be modified after creation. The other options represent immutable data types.
Which statement about Python identifiers is correct?
Identifiers can contain spaces.
Identifiers must start with a digit.
Identifiers can contain letters, digits, and underscores, but cannot start with a digit.
Identifiers are case-insensitive.
Python identifiers can include letters, digits, and underscores and are case-sensitive. They cannot begin with a digit, and spaces are not permitted.
Why is indentation important in Python?
It is optional and only used for aesthetics.
It is used only for commenting code.
It defines the structure and boundaries of code blocks.
It determines variable data types.
Indentation in Python is crucial as it defines code blocks such as loops and conditionals. Incorrect indentation leads to syntax errors.
What is the primary purpose of a variable in Python?
To store and reference data values.
To store keywords used in Python syntax.
To define a function.
To execute code automatically.
Variables in Python are used to hold data values that can be referenced and manipulated throughout a program. They serve as containers for dynamic data.
How does a for loop differ from a while loop in Python?
There is no difference between a for loop and a while loop.
A for loop does not require initialization, while a while loop does.
A for loop iterates over a sequence of items, whereas a while loop continues until a condition is false.
A for loop can only iterate over numbers, while a while loop works with any data type.
A for loop in Python automatically iterates over any iterable, such as lists or strings, while a while loop repeatedly executes as long as a condition remains true. This difference influences how loops are used based on the data available.
Which function is used to determine the length of an object like a list or string in Python?
count()
size()
length()
len()
The len() function returns the number of items in an object, such as a list or a string. The other functions are either not built-in or serve different purposes in Python.
Which file mode should be used to open a file for reading in Python?
'a'
'x'
'w'
'r'
The 'r' mode is used to open a file solely for reading. The other modes are intended for writing ('w'), appending ('a'), or exclusive creation ('x'), and are not appropriate when only reading data.
Which Python data structure stores key-value pairs and is built-in?
List
Set
Dictionary
Tuple
Python dictionaries are built-in data structures that are designed to store key-value pairs. They are particularly useful for mapping and lookup tasks.
What is the result of the list comprehension [x**2 for x in range(5)]?
[0, 1, 4, 9, 16]
[0, 1, 2, 3, 4]
[0, 2, 6, 12, 20]
[1, 4, 9, 16, 25]
The list comprehension squares each integer from 0 to 4, resulting in [0, 1, 4, 9, 16]. The alternative options reflect common errors in applying the square operation.
Which keyword is used to define a function in Python?
function
define
func
def
The 'def' keyword is used to begin a function definition in Python. The other options do not adhere to Python's syntax for defining functions.
What is the output of print(2 + 3 * 4) in Python?
20
14
18
24
Python follows operator precedence, where multiplication is performed before addition. Thus, 3 * 4 equals 12, and adding 2 gives an output of 14.
Which method removes whitespace from the beginning and end of a string in Python?
strip()
lstrip()
trim()
rstrip()
The strip() method eliminates whitespace from both the beginning and end of a string. Although lstrip() and rstrip() remove whitespace from one end, they do not address both ends simultaneously.
What is the primary purpose of using try and except blocks in Python?
To iterate over collections.
To handle exceptions and errors gracefully.
To import modules.
To define classes.
The try and except blocks are used for exception handling in Python, enabling programmers to catch errors and prevent program crashes. This structured error management is essential for writing robust code.
Which method converts all characters in a string to lowercase in Python?
lower()
tolower()
to_lower()
smallcase()
The lower() method returns a new string with all uppercase characters converted to lowercase. The other options are not recognized as valid string methods in Python.
