As I am trying to use python to build a rather large software solution for use in bioinformatics, I am slowly realizing that there are lots of concepts I really need, that were never taught in my CS courses. Among them:

• What is functional programming and how it is different from object-oriented programming
• What is lambda calculus
• That Python is a functional programming language and that trying to use it for OO will be painful and frustrating
• How do you do to program a large software solution you would like to reuse or at least maintain later on
• What are closures are and how useful they are
