Sorting using lambda not working in Py2.1?

Hi!

   I am impressed by the number of mistakes you did! :)

   AttributeError: x has no attribute "sort".
I think "x" is a list:
x = [9,5,4,3,1,2]

   x.sort() sorts in-place and returns None. So this print prints None. You
want to print x, not x.sort().

   Hmm...

>>> x = [9,5,4,3,1,2]
>>> x.sort(lambda x,y: x<y)
>>> print x
[9, 5, 4, 3, 1, 2]
>>> x.sort(lambda x,y: cmp(x, y))
>>> print x
[1, 2, 3, 4, 5, 9]
>>> x.sort(lambda x,y: x>y)
>>> print x
[1, 2, 3, 4, 5, 9]

   Something strange here...

Oleg.

           Programmers don't die, they just GOSUB without RETURN.
