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
