If you are using a virtual environment and want to use the old version of Python and pip then you have to install PIP separately. If you are doing so, we highly suggest you to download the latest version of Python.

Please note that you need to install pip separately only if you are using an old version of the Python programming language. Open the terminal (macOS) and enter the following command: How to check the version of pip installed on my system? If you are using the Python 2.7 (or greater) or Python 3.4 (or greater) versions of python then you do not need to install PIP, because Python comes with a compatible version of PIP by default. By now, PyPI has more than 130,000 packages on its repository. PIP itself uses PyPI as the source to install all the python packages. PyPI stands for “ Python Package Index” and it is the official central library for all the python packages, which means it consists of all the registered and licensed python packages.

If you want to install popular third-party packages, such as NumPy, pandas, and TensorFlow for your project, you just need to open the command prompt or terminal on your system and type the pip install command to install any package or Library which are at PyPI. By using the pip command, you can install, reinstall, update, and uninstall the PyPI package. PIP stands for “Preferred Installer Program” and it is a command-line utility that helps you to manage your python third-party packages. In python, you do not need to manage any of the installed packages, PIP will take care of everything. Python is well known for its simplicity and ease, that’s why it also makes sure that you can easily install any third-party package and/or library for your project just by writing a simple one-line pip command.
