Install PIP on Ubuntu

Install PIP on Ubuntu 17.10 Artful Aardvark

Python is a widely used general purpose programming language. Python is very programmer friendly and easy to learn. Python is a modular programming language. So people all over the world write python code to solve different problems and share these codes with other people who have the same problems. The repository where all of these are kept is called PyPi or Python Package Index. PIP is just a tool used to automatically install these packages from PyPi repository. A PyPi package may depend on other PyPi packages. PIP also resolves package dependencies. PIP can also install packages downloaded manually from PyPi. So basically PIP is the package manager of Python, just like apt is for Ubuntu. PIP is a very useful tool for Python programmers.

In this article, I will show you how to install the latest version of Python PIP on Ubuntu 17.10 Artful Aardvark. Let’s get started.

There are 2 versions of Python programming languages that are still widely used today. They are Python 2 and Python 3. Work is in progress to convert all Python 2 codes to Python 3. Once the conversion is complete, Python 3 will dominate and the days for Python 2 will be over. Since both of these versions of Python programming languages are still in use today, I will show you how to install and upgrade PIP on Python 2 and Python 3.
