How to import modules in Python?

The python module is nothing but a code of variables, functions, or class defined. This filename becomes the module name. Users can define a module or can use inbuild modules like math modules.

To use the module, you have to import it using the import keyword. Let’s see examples for it:-

Import inbuild python math modules

import math

# Square root of number
sqrValue = math.sqrt(25)
print(sqrValue)

Output: 5.0

Custome module import example

main.py

var = "Hello main file"
num = 9876543210


def greeting(name):
    print("Hello, " + name)

Test.py

import main

main.greeting("John")
print(main.num)

Hello, John
9876543210
