ABSTRACT
The wonderful feature of Python language is its wide range of Application Programming Interface support. The package in Python is basically synonymous with the distribution. APIs are available in the form of a package. Some of the packages are inbuilt and will be available as we install the core. Most of the packages are external, and they can be installed on demand. In this chapter, our main focus is to emphasize different useful packages that are related to machine learning, Arduino, Data Science, and other technologies. One of the helpful entities in this context is PyPI, the Python Package Index, which is a software repository for Python programming.
