As the author of many applications and libraries in Erlang and Python I often switch from one to the other during the day. The usage of Erlang definitely changed the way I am coding in Python . This talk will cover some techniques that are used in Erlang and other functional programming languages and how they can be used to solve problems in more performant, robust and/or concise ways than the standard practices in Python. It will also discuss some possible changes to Python and how such changes could improve its usage by the community.
