How do I read code where "from <module> import *" is used?

Suppose I read code written by someone else where "from import *" is used, how can I determine what module a function is from? Is this the reason why some people frown upon "from import *"?

from ... import * is the bad style not recommended by PEP8 (python style guide). There are no ways to know which module is function from except the editing the code (replacing from ... impot * to 'import ...' and looking for errors). Unfortunately, those errors will occur only when corresponding parts of code is executed.

Yes, this is why from <module> import * is considered bad style. What you can do is remove these * imports one by one, then check which NameErrors you get and solve them one by one by explicit imports.
