[Tutor] Question About Subclasses

[Charlie Derr]

try

cupboard = Classes.Containers("cupboard", 0, "closed")


it will also work without that change if you subsitute

from Classes import *

for

import Classes

but there are a bunch of reasons for *not* doing it this way  -- get in the
habit of using the syntax in the first solution

|
|
|Hello,
|
|I'm having some problems getting Python to create a subclass. I
|have a class
|called Items, and then a subclass of that called Containers.
|Python doesn't
|recognize Containers as a valid subclass.
|
|This is what I have in a file called "Classes.py":
|
|class Items:
|    def __init__(self, name, ip):
|        self.name = name
|        self.inPossesion = ip
|
|class Containers(Items):
|    def __init__(self, name, ip, oc):
|        Items.__init__(self, name, ip)
|        self.openClosed = oc
|
|Then within another file called "game.py" I have the following code:
|
|import Classes
|
|cupboard = Containers("cupboard", 0, "closed")
|
|key = Items ("worn key", 0)
|
|When I go to run this code, Python spits this back at me:
|
|>>>
|Traceback (innermost last):
|  File "C:/Program Files/Python20/game.py", line 3, in ?
|    cupboard = Containers("cupboard", 0, "closed")
|NameError: There is no variable named 'Containers'
|
|What am I doing wrong?
|
|Thanks,
|
|Britt
