I agree with the other commenters and recommend this be closed.  There doesn't seem to be a a useful issue here.  It seems more like a pedantic twisting of words that ignores how Python works (i.e. that you can specify a specific class to inherit from and that it is possible to either shadow or alter builtins).  I don't see any magic here beyond changing a variable name to refer to a new object while previous references (or builtin references) to that name continue to refer to old object.
