Why: "The PyMongo distribution contains tools for interacting with MongoDB database from Python. The bson package is an implementation of the BSON format for Python. The pymongo package is a native Python driver for MongoDB." This is the official MongoDB driver for Python. MongoDB is a fairly popular database. I'm sure many developers using Solus would benefit from having the Python driver.
