(1) Don't import it in the first place.

(2) Import it with a different name, possibly private:

from module import x as _x

(3) Delete it when you're done:

from module import x
class Y(x):
    pass
del x

(4) Don't be so fussy and just accept that importing adds names to the 
namespace, as does any other assignment or class or function definition.
