To understand libraries, techniques and benchmarks to help you speed up your data storage, retrieval and processing.


Working with data in Python requires making a number of choices, ranging from the simple to the complex.

  • Should I use pickle, CSV or JSON? (Ans: CSV).
  • What do I read it with: csv.DictReader or csv.reader? (Ans: Pandas).
  • How should I parse dates? (Ans: Anything but Pandas / dateutil)
  • How do I optimise numpy calculations? (Ans: Learn vector algebra)
  • How do I run a function in parallel?
  • How to make my program restartable?
  • How do I use multiple cores?

This session will explain how to benchmark code and share insights on the patterns of programming that make your application faster.


A good working knowledge of Python and the standard libraries
