Intro To Python Programming - Simple Python Functions

The video tutorial introduces the concept of functions in Python, explaining their role in organizing code and their reusability across programs. It demonstrates how to define and call a simple function using the 'def' keyword and highlights the importance of function calls for execution. The tutorial further explores the concept of variable scope, distinguishing between local and global variables, and how they interact within and outside functions.

What is the primary purpose of using functions in Python?

• To make code harder to read

• To make code run faster

• To organize and reuse code

• To increase the size of the program

What must you do to execute the code within a function?

• Define the function

• Call the function

• Write the function name in comments

• Save the function in a separate file

What happens when you call a function multiple times in a program?

• The function does not run at all

• The function runs twice

• The function runs as many times as it is called

• The function runs only once

Where can a local variable be accessed?

• Only within the function it is defined

• Anywhere in the program

• In any function within the same module

• In any function within the same file

What error occurs if you try to access a local variable outside its function?

• NameError

• TypeError

• ValueError

• SyntaxError

What is the scope of a variable defined outside of any function?

• Local scope

• Global scope

• Function scope

• Module scope

How can global and local variables be used together in a function?

• They cannot be used together

• By converting local variables to global

• By defining them with the same name

• By using the global variable inside the function
