The PIP tool is a package manager or in simpler terms, a software warehouse that is used for installing and managing Python libraries and packages. By using this tool, you can quickly and easily add various libraries into your projects or update them.
Working with PIP is very simple and does not require a lot of effort. If you have previously tried to install a new Python library, you have probably worked with PIP. This tool is generally assumed to be installed along with Python, so there is no need to install it separately.
One of the attractive features of PIP is its simplicity and functionality. To install a package, just enter the command pip install package-name in your terminal and let PIP handle the rest. This tool will automatically install all dependencies required for the libraries as well.
For developers or developers, PIP is a very useful tool that speeds up the workflow and helps alleviate many complexities. With PIP, you can manage your necessary packages through a simple text file. This file is usually identified by the name requirements.txt.
In this guide, we will provide examples of how to use PIP for installing libraries and managing them so that you can better utilize it in your projects.
