Things to bear in mind before you install pip3:.Why install pip3 instead of using easy_install?.PIP is to Python what npm is to JavaScript and gem is to Ruby. The Python standard library already comes chock full of packages and modules to help with your scripts and applications, but because the Python community is super active, people are constantly developing additional packages to make things easier. (A package contains all the files you need for a module, and modules are Python code libraries that you can include in your projects.) PIP is a package manager for Python, which means it allows you to install and manage libraries and dependencies that are supplemental to the standard library. (And yes, PIP is better than easy_install.)

And if you want to get better at Python, you’ll want to install PIP3. Python is a great programming language for beginners, because it’s less intimidating than most of the other languages you’ll eventually have to work your way through. If you need to use another version of Python or a different interpreter such as PyPy, see the Multiple Interpreters section.A good programming language is hard to find, but if you’re serious about being a programmer or web developer, and you’ve already got your hands on some great web hosting to store all those websites you’ll end up burning through in your early days, it definitely helps to know more than one language. Let’s create a virtual environment called project_venv with the main Python 3 version in Fedora. Another advantage is that you can have more versions of the same module in different virtual environments. It will keep all modules for one project at one place and it will not break your local system. The best practise is using pip in the virtual environment. Installing modules with pip to system directories is not recommended, as it can override system libraries and lead to an unstable system. You can either install such modules to a virtual environment, or to your home directory with the -user user switch. Only install software you trust, and always double-check install commands for typos in package names. Note that software on PyPI is not part of Fedora, and has different standards of quality, security and licensing: essentially, anyone can upload code there. You can use pip to install it from the Python Package Index (PyPI).

Or if you need it in an isolated environment, If a Python package you need is not packaged for Fedora,

Python 3 install pip
