Python Modules

How to Create a Python Module?

To understand Modules in Python, first create a file with name Module1.py and write below code –

def Function1(a, b):
    print(a+b)

Import Module in Python

Once the module is ready, we will use this module in separate source code by using import statement.
When interpreter found an import statement in Python source code, it import the module and made available for current source code if found in specified location.

Now create a new file with name TestModule.py and write below code –

import Module1
Module1.Function1(10,20)

Execute the TestModule.py file by using below command –

python TestModule.py

And you will see that code written in Module1.py gets executed.

Variables in Modules

As mentioned above that, a Python module can contains functions and variables as well.

Product = {
     "ProductId":1,
     "Name":"Product1",
     "Category":"Electronics",
     "Cost":15000.00
 }

Above Code can be used as Module using Import statement –

import Module1
Product = Module1.Product["Name"]
Cost = Module1.Product["Cost"]
print(Product)
print(Cost)

There are readymade Modules available in Python. Some of the Modules are –
pyodbc, math etc

import Module1 as m
m.Function1(10,20)
