Relative imports in Python

For some time (as relative imports canceled) I can’t normally solve the following question:

Suppose, the structure of the program

  App/ __init __. Py foo/ __init __. Py handler.py    
 as from the module  handler.py  load something from the packet  foo 
  
 The whole point is that the name of the package  foo  is unknown, unknown, it is unknown. I download it with  Importlib . 
  
 while I found such a crutch: I cut the variable  __ name __ , which in  handler.py  is equal  'foo.Handler' , i.e. So 
  
  foo_name = __name __. rsplit ( '.' ,  1 ) [ 0 ]     
 and then I load the module I need 
  
  Needle_module Importlib.import_module ( ''. ' + & lt; the name of the module & gt;, foo_name)     
 but, somehow, this is not koserly ...
