Learn 3: Create Your First Class

5. Init All the Things!

Let’s now create a basic class instance within our global init( ) function (not the __init__() that is part of the GlobalVariables class) a

We do this by instantiating the container class

Find the Variable Initialization Cell
Add the following code.
Pay attention to indentation! (check against the image to be sure)

global var

var = GlobalVariables()

You may have noticed that we haven’t passed the self argument to the GlobalVariables( ) class constructor function. self is a special class attribute. It references the current class instance. All class functions (or methods) use this as an implicit first argument. This means that you don’t need to state it when you call the function, it’s automatically added for you by the class definition. This makes the instance’s attributes and other methods accessible within the function definition.
