Hi! I have a problem in a program. And I don't understand what is going on. I can code something, that the "error" doesn't occur anymore. But I still don't know the reason and this is unsatisfactory: Did I understood something wrong or is there a bug? To make it short, I boiled down the program to the crucial part. It looks like this:
----------- START ------------ #!/usr/bin/env python class cClass: """ Base class to handle playlists, i.e. the files, the name, etc. """ def __init__(self, LL=[]): self.list=LL def addFile(self,L): self.list.append(L) def main(): l1 = ['a','b','c'] lNames=['n1','n2','n3'] for name in lNames: objC=cClass() for each in l1: objC.addFile(each) print objC.list del objC if __name__ == "__main__": main() ----------- END ---------------- If I start it, I get the following output: ['a', 'b', 'c'] ['a', 'b', 'c', 'a', 'b', 'c'] ['a', 'b', 'c', 'a', 'b', 'c', 'a', 'b', 'c'] Why does this list grow? I thought, with every new instance the list LL is set to []? How can bring light in this? Best, Dirk -- http://mail.python.org/mailman/listinfo/python-list
