Python is a programming language that is heavily used in machine learning, in part because of the ectebsive libarraies that have been developed and in part because of the success of Jupyter notebook, which makes it easy to experiment, modify and share not just programs or the output of a session of actvity, but also the details of the process itself in a manner that can be replayed and modified by others.
