> Hi, When running below code, I get error saying: > instance attribute "a" defined outside __init__ That's a warning, not an error. And it's a warning from pylint, not from Python itself. It's trying to suggest better style, that's all. It's unusual to define instance variables in functions other __init__. > class Foo: > var = 9 > def add(self, a, b): > self.a = a > self.b = b > print a+b > def __init__(self): > print 10 > bar = Foo() # create object > bar.add(4, 7) # call method by object.method > print bar.var # access class variable > why the output prints: > 10 > 11 > 9 10 is printed by Foo.__init__(), when an instance of Foo is created. 11 is printed by calling bar.add(4, 7). 9 is printed by your statement 'print bar.var'. Your program has those statements in that order, so they are printed in that order. Why did you expect a different order? -- John Gordon Imagine what it must be like for a real medical doctor to gor...@panix.com watch 'House', or a real serial killer to watch 'Dexter'. -- https://mail.python.org/mailman/listinfo/python-list
