Which of the following is a correctly formed Python variable name?
variable1
variable-1
1variable
variable 1
Variable names in Python must start with a letter or underscore and cannot contain hyphens or spaces. 'variable1' meets these criteria, making it the correct choice.
Which data type is used to store textual data in Python?
int
bool
str
float
In Python, the 'str' type is used to handle textual data. Other options represent numeric and Boolean types.
Which keyword is used to define a function in Python?
fun
define
function
def
The 'def' keyword is used to create functions in Python. Other options are not recognized as proper function definition keywords in Python.
Which loop construct iterates over a sequence, such as a list, in Python?
do-while
for
repeat-until
while
The 'for' loop in Python is designed to iterate over sequences like lists. The other loop types are either not used or not supported in Python.
How do you create a single-line comment in Python?
# This is a comment
/* This is a comment */
// This is a comment
Python uses the '#' symbol to mark the beginning of a single-line comment. The other options are comment styles from different programming languages.
Given a list L = [3, 5, 7, 9], what is the output of L[2]?
5
9
3
7
Python list indexing starts at 0, so L[2] retrieves the third element, which is 7. This basic concept is fundamental in Python programming.
What does the slice L[1:3] return for the list L = [3, 5, 7, 9]?
[5, 7]
[3, 7]
[3, 5]
[7, 9]
The slice L[1:3] returns a sublist starting from index 1 up to, but not including, index 3. This results in the sublist [5, 7].
When iterating over a dictionary (e.g., for key in my_dict), what is being iterated by default?
Key-value pairs
Keys
Values
Indices
Iterating over a dictionary by default yields its keys. To access values or key-value pairs, explicit methods like .values() or .items() need to be used.
Which term describes a function parameter that has an assigned default value in Python?
Positional parameter
Default parameter
Variadic parameter
Immutable parameter
A function parameter with an assigned default value is referred to as a default parameter. This allows the function to be called with fewer arguments if needed.
Which Python library is most commonly used for data analysis involving tabular data?
Matplotlib
NumPy
SciPy
Pandas
Pandas is widely used for data analysis and provides powerful DataFrame structures for handling tabular data. Other libraries serve different purposes such as numerical operations and plotting.
Why is parameter sensitivity analysis important in simulations of cognitive processes?
It reduces the need for data collection
It automatically improves the model's accuracy
It simplifies the model's code structure
It tests how variations in parameters affect outcomes
Parameter sensitivity analysis is crucial because it evaluates how changes in model parameters influence outcomes. This understanding is key in refining models to accurately represent cognitive processes.
What is the primary purpose of using simulations in computational modeling of cognitive processes?
To completely substitute for actual experimental data
To increase the computational load unnecessarily
To generate aesthetically pleasing graphics
To replicate and explore complex brain mechanisms
Simulations allow researchers to model and investigate complex brain mechanisms that are difficult to observe directly. They provide a controlled environment to test hypotheses related to cognitive processes.
Which principle is crucial for writing efficient Python code for data analysis?
Prioritizing algorithmic efficiency and scalability
Using nested loops for every operation
Avoiding any third-party libraries
Hard-coding all data inputs
Efficient code in data analysis emphasizes algorithmic efficiency and scalability to handle large datasets effectively. These considerations help optimize performance and resource utilization.
Which method is a common initial approach for debugging Python code?
Disabling error messages
Manually reading the bytecode
Using print statements to track variable states
Relying solely on comments to identify errors
Using print statements is a straightforward and commonly used technique for debugging in Python. It allows programmers to monitor variable values and the flow of execution during runtime.
What is an advantage of using experimental frameworks like PsychoPy in Python?
They simplify the construction and execution of psychological experiments
They complicate experimental design with unnecessary features
They are exclusively designed for game development
They eliminate the need for programming knowledge
Experimental frameworks such as PsychoPy streamline the process of designing and running psychological experiments. They provide pre-built tools and interfaces, allowing researchers to focus more on experimental design rather than low-level programming details.
