Python 3 for Beginners: Python Functions and Return Statements

The video tutorial covers the concept of docstrings in Python, explaining how to create them using triple quotes and access them with the help function. It then discusses how functions can return data using the return statement, with examples of returning strings and Booleans. The tutorial also demonstrates how functions can call other functions, providing a practical example of nested function calls.

What is the primary purpose of a docstring in a function?

• To execute the function

• To provide a summary of the function's purpose

• To store the function's output

• To define the function's parameters

How can you access a function's docstring?

• By using the return statement

• By using the help function

• By using the print function

• By using the input function

What happens when a return statement is executed in a function?

• The function continues to execute the remaining code

• The function stops executing and returns a value

• The function restarts from the beginning

• The function prints the return value to the console

Which data type can a function return using the return statement?

• Only Booleans

• Any data type

• Only strings

• Only integers

What is demonstrated by a function that calls other functions?

• How to create a loop within a function

• How to pass data between functions

• How to use global variables

• How to define multiple functions
