I don't think so. It looks to me like you are trying to identify something internal to a module that way. Import works on the module itself and builds the interpreter’s symbol table for the whole module to allow resolving everything correctly.

</div>
<div>from xxx import yyy Kind of does what you ask for one method at a time. And you can probably use the as functionality too, you do still pollute namespace that way, but not quite as willy-nilly.</div>
<div><br>
</div>
<div>Really though, just because it might feel a little more java-ish for the from imports and how they avoid needing to prepend module names, thats exactly a backwards goal if you want the end result to be robust in Python.</div>
