Interesting talk on Python vs. Ruby and how he would like Python to have just a bit more syntactic flexibility.

The name is used in Pascal, which probably means it originated from
Fortran or Algol.
A subroutine is a generic piece of code which can be re-used by some
unspecified mechanism (GOSUB in Basic, by calling it in most other
languages). A function is a subroutine that returns a result, and a
procedure is a subroutine that doesn't return anything (not even None, or
the equivalent thereof) and operates entirely by side-effect.
