In most cases, this translates to: the imported module defines __names__, which holds the list of names (of the objects) to be exported. Check it.
Below, a,b,c,f,g,X,Y are defined, but only c,g,Y are exported. This means "from mod import *" will only import these names. Without __names__ defined, it would import all.
### module mod.py ###
__names__ = ['c','g','Y']
a = ...
b = ...
c = ...
