Additional Python Facilities

Additional Python Facilities - module Y115

Python is a wide-ranging language, so you won't have learnt everything about it on the early stages of your course. In this module, we assume fundamentals knowledge, and we go on to cover some of the more advanced features of the language that you'll need as you go on to write larger applications of the type that Python's so well suited to.
