Is there some sort of rule-of-thumb to determine if a function is
in-place or returns a value?
my rule of thumb is to ask:
Python 2.7.5 (default, May 15 2013, 22:44:16)
[MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> help([].sort)
Help on built-in function sort:
sort(...)
L.sort(cmp=None, key=None, reverse=False) -- stable sort *IN PLACE*;
cmp(x, y) -> -1, 0, 1
>>> help([].reverse)
Help on built-in function reverse:
reverse(...)
L.reverse() -- reverse *IN PLACE*
>>>
The *IN PLACE* tells me.
HTH,
Emile
