 Python is a widely-used, interpreted, object-oriented, high level programming language. It is very popular, particularly among domain scientists such as biologists. This language unit is designed for people that have not taken CS128 at Earlham. If you are in a major other than CS, or have previous programming experience in a language other than Python, this module might be perfect for you.
