Python None Keyword
Definition and Usage
The None keyword is used to define a null value, or no value at all.
None is different from 0, False, or an empty string. None is its own data type (NoneType), and only None can be None.

Example
What will happen if you perform a boolean if test? Is None True or False:
x = None if x: print("Do you think None is True") else: print("None is not True...")
