Coming from python, what should be the second programming language to learn?

Question

i was thinking learn a more low level language like C, but before it i'd like some opnion about:

1. what's the second language do you recommend to learn?
2. learn a low level language will make me a better programmer?
3. it's really necessary learn a second programming language?

Answer 1

Going backwards:

(3) Absolutely - you'll increase your ability by orders of magnitude by learning multiple languages.

(2) A low level language will make you a better programmer - alternatively a functional language will help as well.

(1) Low-level: go with C. Functional, try Scheme or Haskell. C also gives you the ability to write extension modules to Python if you ever have the need.
