Hi all,
can anyone explain the behaviour of the following code sniplet:
---> schnipp <---
class Base(object):
def __init__( self, lst=[] ):
self.varlist = lst
def addVar( self, var ):
self.varlist.append(var)
class Derived(Base):
def __init__( self, var ):
Base.__init__(self)
self.addVar(var)
vars = ['foo', 'bar']
for ivar in vars:
obj = Derived(ivar)
print ivar, obj, obj.varlist
---> schnapp <---
After running (Python 2.5.1), I get the following output:
foo <__main__.Derived object at 0xb7c608cc> ['foo']
bar <__main__.Derived object at 0xb7c6092c> ['foo', 'bar']
So, I get two different objects, but how does the 'foo' get into the second
varlist? I'm a little bit confused about this, any ideas?
Thanks in advance
Jan
