[Tutor] Fwd: Class Extend Help

[Omer]

Hey!

Thx for the help,

@Martin,
At the moment my only need is basic retrievals of source code of basic files
from the internet, so no need for urllib2 or response objects just yet.


Now, copying and pasting line by line into the interactive mode I get this:

>>> from urllib import urlopen
>>> class fetch(urlopen):
...     def __init__(self,*args):
...         urlopen.__init__(self, *args)
...         self.content = self.read()
...

Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
TypeError: Error when calling the metaclass bases
    function() argument 1 must be code, not str

Anybody, any idea what's up with that?
