Let's get started! 🔥🔥🔥 In this video, we will write a few PYTHON 🐍 scripts to demonstrate how to define and use functions ♻️. In the examples, we create a function that returns a single value by using the return keyword, then we add a new function that returns a list. Finally, we write a new function that demonstrates variable scope in a function to help you understand the scope of variables declared both inside and outside a function. In this tutorial, you will learn some basics in about 5 minutes!

In this video, you will learn how to:
★ 0:09 Function that returns a value
★ 1:19 Function that returns a list
★ 3:06 Function that demonstrates variable scope in a function

Tips and Tricks:
► Capture the returned value of a function by assigning it to a variable.
► Returned value of a function can also be a list that contains multiple values.
► Scope is a value's accessibility inside and outside a code structure like a function's code block.
► Value cannot be accessed outside the code block of a function in which it was declared and initialized because the variable is hidden and unavailable outside the code block.
► Variables defined outside a function don't affect variables defined inside a function unless your code returns the inside value and then uses it.
