Most of the bitwise operators are binary, which means that they expect two operands to work with, typically referred to as the left operand and the right operand. NettetEnum: It is a base class for creating enumerated constants. IntEnum: It is also a base class for creating enumerated constants and subclass of int. Flag: It is used to combine enumerated constants by bitwise operators. IntFlag: It is also a subclass of int and similar to a flag that is used to combine enumerated constants by bitwise operations.
