Creating a function

In python functions are used so that you don't have to re-write code. When writing functions start by defining it

def my_function() -> None:

Here the -> None is used to show that nothing gets returned by this function. It is another form of documentation. Next you need to add a docstring. Docstrings are like comments but for functions, you can still use comments in functions though

def my_function():
	"""This is a docstring"""

Docstrings can also be multi-line and should be broken up if lines get too long.
