So You Think You Know Python?

Python is a language full of delightful surprises, if you know where to look. This talk takes you on a guided tour of its most interesting quirks, from easter eggs buried in the standard library, to real-world examples of how the language's gotchas have tripped up even the most seasoned developers.

This talk goes through code, documentation, PEPs, mailing list threads, discussions in issue trackers, webcomics, and other sources to get the answers to the following questions (and more):

  • Is midnight falsy?
  • Why does ~True equal -2?
  • What is the hash of infinity?
  • How many references to xkcd webcomics are in the standard library?
  • Why can't raw strings end with an odd number of backslashes?
