Hi,
How do python instances work? Why does the code at the end of my posting produce this output:
list in a: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] list in b: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
instead of
list in a: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] list in b: []
----------------------------
class MyClass: list = []
def add(self, x): self.list.append(x)
def printer(self): print self.list
a = MyClass() b = MyClass()
for n in range(10): a.add(n)
print "list in a:" a.printer() print "list in b:" b.printer()
/H
because list is a class member not an instance member (not sure about the vocabulary) if in __init__ you set self.list=[] you'll get the result you want! By declaring list=[] in the class it is shared between all instances!
