Modules in Python

A Python file containing code you want to include in program use 'import' to include module (built-in or your own) useful to break up a large program to reusable separate files

Let's break this definition.

• First we use python module of math.
• we will make our own module of math.

simply open your code editor and write.
Here we will use python built-in module.

import math

print(math.pi)

output:

3.141592653589793

Now we will take an example of module you will create.

1. Create a folder name "mathfunction".
2. now make two python file name "main.py" and "math.py"

math.py

pi=3.141

def square(x):
    return x**2
 # type: ignore

def cube(x):
    return x**3


def circumference(radius):
    return 2*pi*radius

main.py

import math
y=6
print(math.pi)
print(math.cube(y))
print(math.square(y))

Output from main.py
3.141
216
36

You have seen that pi value is the value I have given it.
