Sometimes we have to use someone else’s code in our program because it saves a lot of our time. Today, we will learn a technique to use code that is not written by us but will enhance the quality of our program, save us time, and of course, it is legal and free.
Let us understand what utilities like module and pip are
Module – Module or library is a file that contains definitions of several functions, classes, variables, etc. which is written by someone else for us to use for free.
Pip – Pip is a package manager in python i.e. pip command is used to download any external module in python. It is something like which helps us to get something from somewhere.
We can install any module in our system by using pip command :
Example, for installing flask I will do something like this:
After the pressing enter key you will see something like this:
After installing any module in python you can import it in your program or in your Python projects. For example, to use flask I will say import flask at the top of my Python program.
There are 2 types of modules in Python :
Built-in modules are the modules that are pre-installed in python i.e. there is no need to download them before using. These modules come with python interpreter itself.
Example – random, os etc.
To get a complete list of built-in modules of python head to the following page of the official documentation - https://docs.python.org/3/py-modindex.html
These are the modules that are not pre-installed in python i.e. we need to download them before using in our program.
Example – Flask, Pandas, TensorFlow, etc.
