Although it is well understood that python has support for some functional constructs, the extent to which python can be used for functional programming is not always well appreciated.

A backgrounder to some of the elements in the early stages of the talk could be found at Functional programming with Python - Part 1

The talk shall not focus on the debate between functional programming (FP) vs others (eg OO) or between various languages. Python is not a ground up functional programming language, and thus does not have all the constructs that are required by FP. However, given the usefulness of FP in many contexts, this talk will help audience better appreciate how it can still use python quite effectively in the contexts where it does seem like the right thing to do. It will also help the audience be better prepared to evaluate OO + FP programming since thats one area (being multiparadigm with support for first class functions) that python is good at.
