You have something like :


######## a module

self = "some value"

print id( self )

class Foo :
    def __init__( self , *TestClasses ) :
        print id( self )


The 2 'print' lines will print different things -- the 'self' inside
the __init__ function is a different 'self' than outside the function.

The solution is to change the name of one or more of them.  It is also
conceivable that you have

class Foo :
    def func( self ) :
        class Bar :
            def __init__( self ) :
                pass

which would cause the same problem, when nested_scopes are used.  If
you show the rest of the code, then it will be more obvious what is
really causing the warning message, and it will be easier to suggest
alternative coding/naming styles.
