Google style guide requires to import modules. Say I have a non trivial class and several non-trivial derived classes. It seems that I have to put them all in the one file otherwise will have to use different prefixes when using them.
Personally I prefer one class per file. Is there a common idiom to avoid unnecessary large files?
E.g. can I rename several imports into one as long as there is no name conflicts?
import data_main as data
import data_derived_a as data
import data_derived_b as data
