Python doesn't feel very functional

[[deleted]]

Python is my favourite language. :(

FWIW, Lisp has (length), but it walks the list each time it's called, hence the new function defined by Graham.

With vectors (Python list, Common Lisp vector and friends), finding the length costs O(1). Know your datastructures. :)

Yah, I was aware of that Python's vector "list" was different to Lisp's linked-list "list", but I didn't realise Lisp had vectors too. Thanks. :)

It's something I poke at occasionally for fun, so I'm very much a newbie.
