And suppose they believe it, are the willing to stop their research to rethink and rewrite their code ;-)

Then I miss something: TEN = 10 TWELVE = 12 def some_function(): global TEN TEN = 9 TWELVE = 11 print TEN, TWELVE some_function() #will print 9,11 print TEN, TWELVE #will print 9,12 Or am I mistaken ? cheers, Stef Mientki -- http://mail.python.org/mailman/listinfo/python-list
