Using Multiple Constructors

[Skip Montanaro]

    Mikhael> Class MyObject:
    Mikhael>     Constructor1(self, number):
    Mikhael>         pass
    Mikhael>     Constructor2(self, string):
    Mikhael>         pass

You can only have one constructor.  Since you can't declare Python object
types, you have to check them at runtime.  One way you might find useful is
to force your users to use keyword args:

    class MyObject:
        def __init__(self, **kwds):
            if kwds.has_key("number"):
                self.number_init(kwds["number"])
            elif kwds.has_key("string"):
                self.string_init(kwds["number"])

There are other ways to break the problem up as well, including providing
various defaults:

    class MyObject:
        def __init__(self, number=None, string=None):
            ...
