Python Functions Quiz

Define a procedure in Python and provide an example.

• def example_procedure: print('This is an example procedure')

• function example_procedure(): print('This is an example procedure')

• def example_procedure(): print('This is an example procedure')

Explain the difference between a function definition and a function call in Python.

• A function definition creates the function, while a function call executes the function.

• A function definition executes the function, while a function call creates the function.

• A function definition defines the input parameters, while a function call defines the output parameters.

• A function definition creates a variable, while a function call executes the variable.

What are parameters in a Python function? Provide an example to illustrate.

• Parameters in a Python function are defined outside the parentheses in the function definition. For example: def greet name:

• Parameters in a Python function are defined inside the parentheses in the function definition. For example: def greet(name):

• Parameters in a Python function are not necessary and can be omitted. For example: def greet():

• Parameters in a Python function are defined after the function body. For example: def greet: name

Differentiate between arguments and parameters in Python functions.

• Parameters and arguments are the same thing in Python functions.

• Parameters are defined in the function signature, while arguments are the actual values passed to the function.

• Arguments are used in the function signature, while parameters are the actual values passed to the function.

• Parameters are passed to the function, while arguments are defined in the function signature.

What is the purpose of the return statement in a Python function? Give an example.

• The purpose of the return statement in a Python function is to print a value to the console.

• The purpose of the return statement in a Python function is to pause the function execution.

• The purpose of the return statement in a Python function is to exit the function and return a value to the caller.

• The purpose of the return statement in a Python function is to skip to the next line of code.

Explain the concept of local variables in Python functions with an example.

• A local variable in Python functions is a variable that can be accessed from any function within the same module.

• Local variables in Python functions are declared using the 'var' keyword.

• An example of a local variable in Python functions is: x = 10

• An example of a local variable in Python functions is as follows: def my_function(): x = 10 print(x) In this example, the variable 'x' is a local variable within the function 'my_function'.

How can you modify a global variable inside a function in Python? Provide an example to illustrate.

• In Python, a global variable inside a function can be modified using the 'global' keyword. For instance: y = 5 def modify_global(): global y y = 15 modify_global() print(y) # Output: 15

• A global variable inside a function can be modified in Python using the 'local' keyword.

• In Python, a global variable inside a function can be modified using the 'nonlocal' keyword.

• A global variable inside a function can be modified in Python using the 'global' keyword outside the function.

Define recursion in Python functions and provide an example.

• A function that only calls other functions

• A function that uses a loop to repeat a process

• A function that calls itself is known as a recursive function. Example: def factorial(n): if n == 1: return 1 else: return n * factorial(n-1)

• A function that takes no arguments
