Assignment operators are used to assign values to variables.
The compound assignment operators consist of two operators as a shorthand.
Comparison operators are used to compare two values.
Booleans represent one of two values: True or False.
Logical operators are used to combine conditional statements.
Membership operators are used to test if a sequence is presented in an object.
Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location.
The None keyword is used to define a null value, or no value at all. None is not the same as 0, False, or an empty string. None is a data type of its own and only None can be None.
