What is PIP?
Before understanding the use of PIP, you must learn about Python. It is an interpreted, general-purpose programming language that is known for its high code readability. It is very productive, and hence programmers love it.
Python comes equipped with a standard library that has a myriad of tools to write programs. But what if you need additional libraries? You can have them for sure. That’s where PIP comes in.
Python’s package manager installs and manages additional libraries that do not form part of the standard Python library. The strength of Python is that it runs on several platforms, like Linux, Windows, macOS, and FreeBSD. It comes equipped with most Linux distributions.
