How do you increment a variable by 1 in Python?

There are two means that do not involve functions for incrementing a variable by 1 in Python. The first method is a common approach known by most where the variable is set to itself with a value of one being added.

The second approach uses an assignment operator += that is the shorthand expression of the first.

As of Python 3.9 there is no ability to increment a variable by one by using the double plus operator as seen in other languages. Doing this produces a syntax error.
