game dev, hard science, rendering, machine learning, web dev, streaming (educoding is written in python) usually maya 3d rendering is written in python. docker-compose is python, ansible is python, fabric is python .... a friend of mine wrote a facedetection 7 years ago using python ....
the only rival (script language) is ruby atm (I ignore the newer languages like kotlin).
Python is one of the most sophisticated script languages there is on the market. In some cases it was even faster than go and other compiled languages due to some algorithmic optimizations and things like pypy (JIT).
^^ I hope this finally answers your question, if you can invest in python ... YES :D you can .... even if you decide that you prefer C# in the end or you find out your a functional guy .... python still is a very good choice.
Edit for the record I don't use python in my daily business so this is not a fanboy opinion.
