What is the purpose of a function in Python?

• The purpose of a function in Python is to encapsulate code for reuse and organization.

• To define variables in Python

• To handle exceptions in Python

• To create classes in Python

How do you define a function in Python?

• def function_name(parameters):

• function_name(parameters) =>

• create function_name(parameters)

• function_name: parameters()

What is the difference between a function and a method in Python?

• A function can only return a value, while a method cannot.

• Methods are defined outside of classes, while functions are defined inside classes.

• A function is independent, while a method is associated with an object.

• A method is a type of function that cannot take parameters.

How can you return multiple values from a function?

• Use a list to return values.

• Return a single value only.

• Return values through global variables.

• Use a tuple to return multiple values from a function.

What is a common debugging technique in Python?

• Using a debugger tool

• Using print statements for debugging

• Writing unit tests

• Ignoring error messages

How can you use print statements for debugging?

• Insert print statements to display variable values and program flow at key points in the code.

• Insert print statements only at the beginning of the code.

• Remove all print statements to avoid clutter in the output.

• Use print statements to write comments in the code.

What is the purpose of the assert statement in debugging?

• To optimize code performance during execution.

• To verify assumptions and catch errors during debugging.

• To automatically fix errors in the code.

• To enhance the user interface of the application.

What tools can be used for debugging in Python?

• pdb, logging, IDEs (PyCharm, VS Code), ipdb, PySnooper

• assertions

• try-except blocks

• print statements

What is the syntax for a for loop in Python?

• for variable in sequence[]

• for (variable : sequence)

• for each variable in sequence:

• for variable in sequence:

How do you iterate over a list using a for loop?

• for item in my_list: print(item)

• for item in range(len(my_list)): print(my_list[item])

• for item in my_list: print(item, end='')

• for item in my_list: item.print()
