PIP
Package management is just about installing software for an operating system, but also for programming environments like Python in the case of pip.
Conda
Like pip, conda is a Python package manager for installing software and
manage dependencies.
However, conda is also a Python distribution, named Anaconda.
It's specialized for data science and machine learning applications.
Sometimes you'll want to use this instead of pip.
