You can't, because the BaseClass from the second import over-writes the
BaseClass from the first.
In general, "from module import *" is a bad idea, because you don't know
what names you are importing: you can have name collisions, where a name
in one module clashes with a name in your code, or another module. That is
what is happening with your code.
The way to prevent that is to use Python's namespaces: instead of "from
module import name", use "import module", and then call module.name.
