Python operator module is one of the inbuilt modules in Python. By import operator you can performs various operations and operates two input numbers in a Python program.
The functions provided by operator module can use various mathematical, relational, logical and bitwise operations on two input numbers
Functions supplied by the operator module.

Python import operator
Simple example code.
import operator
# input numbers from user
x = int(input("Enter first integer number: "))
y = int(input("Enter second integer number: "))
# Adding both input numbers
add = operator.add(x, y)
print("Addition: ", add)
# Subtracting both input numbers
sub = operator.sub(x, y)
print("Subtraction: ", sub)
# Multiply both input numbers
mul = operator.mul(x, y)
print("Multiplication: ", mul)
# Divide both input numbers
truediv = operator.truediv(x, y)
print("True division: ", truediv)
# floor division
fldiv = operator.floordiv(x, y)
print("Floor division: ", fldiv)
# modulus operation
mod = operator.mod(x, y)
print("Modulus: ", mod)
# power value operation
pow = operator.pow(x, y)
print("Exponentiation: ", pow)Output:
