PythonoperatorThis section mainly describes the Python operators. To give a simple example 4 +5 = 9 . In the example,4 and 5 are called operands , and "+" is called an operator.The Python language supports the following types of operators:
The operator module contains various built-in operators of Python, such as logic, comparison, and calculation. here we will summarize the examples of using operators of the operator module in Python for some common operators: the operator module is
Arithmetic operators

In Python, the operator module operator examples are summarized.
The operator module is a built-in operator function interface in python, which defines some arithmetic and relatively built-in operation functions. The operator module is implemented
In Python:
Bitwise operations, both bitwise operations, are the binary forms of the number of participating operations.
1. With Operation: A and B values are 1 o'clock, A, B and the result of the operation is 1, otherwise 0 (operator:&)
2. Or
One of the advantages of using the Python magic method is that it provides an easy way to make objects behave like built-in types. This means that you can avoid performing basic operations with ugly, anti-intuitive, and nonstandard methods. In some
