> "if variable is None"

Is missing :

We all know we should do the following, it's much clearer.

# Example of a dictionary to check None

> # Assign None to a variable

> myvar = None

> # Declare dictionary to check None

> mydictionary = {None: 'None is stored in this variable'}

> print(mydictionary[myvar])

If I expected something, I would try it.
