    replied to unable to inherit
    in Python
    Here is an improvement to fix compatibility with objects that use the deprecated __methods__ and __members__ attributes.
    Now it will show the expected result for dir(objectWrapp erInstance), similar to what you would get if you had inherited from the wrapped object.

    Code:
    class ObjectWrapper(object):
    """ObjectWrapper class redirects unhandled calls to wrapped object.
    
    Intended

      Thanks for the reply.
      The __setattr__ is necessary to set wrapped object attributes on the wrapped object rather than the object wrapper (when assigning an attr directly and not calling a set method). This probably wasn't a concern for your DBConnectionWra pper. Consider the following example:

      Code:
      class Foo(object):
    def __init__(self, bar='default'):
        self.bar = bar
    def getUpperCaseBar(self):
      ...

        unable to inherit

        I've run into this issue a couple of times. I want to inherit from a class in order to extend it's functionality. The problem is that the class is defined in c in a shared library and doesn't seem to be designed so that it will allow inheritance (no __class__ defined, etc).
        For example the Client object from pysvn.

        [CODE=python]
        import pysvn
        class MyClient(pysvn. _pysvn._Client) :
        pass
        [/CO...

          Is there a way to determine the calling module name as well? Ie, I want to print "called by MyModule.SubMod ule.Foo()" not just "called by Foo()"
          I think I saw the file path for the module in there but I don't want to have to try to determine the submodules from the path if possible.

          Cheers,
          Pete

            started a topic inherit from file and create stdout instance?
            in Python

            inherit from file and create stdout instance?

            How can I inherit from file but stil create an instance that writes to stdout?
            -----------
            I'm writing a file-like object that has verbosity options (among some other things). I know I could just set self.file to a file object rather than inheriting from file. I started with something like this (simplified for clarity):
            Code:
            class Output(object):
    def __init__(self, file=sys.stdout, verbosity=1):
            ...
