I have a list of numbers... actully I have two lists, List 1 is a list of
number strings and List2 is one of numbers.
List 1 example:
List1 = [ '20040124123000', '20040124123001', '20040125012456']
List 2 example:
List2 = [ 20040124123000L, 20040124123001L, '20040125012456L]
When I try either:
List1 = List1.sort ... or
List2 = List2.sirt
and then...
print List1... or
print List2
I get None.
Why is this?
How do I remedy this problem? 5 1509

Read the library reference manual on builtin objects - sequences - lists -
methods.
Seriously.

Yeah, most everyone who uses sort() for the first time gets bit by this.
Sort() sorts the list in place, and returns None: list1=[20, 40, 60, 80, 10, 30, 50] list1
[20, 40, 60, 80, 10, 30, 50] list1.sort() list1
[10, 20, 30, 40, 50, 60, 80]
So, to sort list1, you just use list1.sort(), not foo = list1.sort()
Amy,
Switch from windoze to linux and provide screen dumps.

I don't understand part of your comment. Windows can provide screen
dumps also. That's not a reason to switch. :-)
