getattr helps. However, your example won't work: it misses either a 
staticmethod-declaration, or a self-argument, or a classmethod and 
cls-argument. So unless we know if bar shall be an instance.method or 
not, it's hard to tell what exactly you want. Because you could want

getattr(getattr(mymodule, "foo"), "bar")

Or

getattr(getattr(mymodule, "foo")(), "bar")

(notice the parentheses)

or

getattr(getattr(locals(), "foo"), "bar")

or

getattr(getattr(globals(), "foo"), "bar")
