hello, I'm trying to sort a list, using the same list at the commandline works, but in a program it doesn't. Here is the code print 'xx1',type(ordered_list) print 'xx2',ordered_list print 'xx3',ordered_list.sort() And this is the result xx1 <type 'list'> xx2 [14, 12, 10] xx3 None What am I doing wrong ? thanks, Stef Mientki
