python - How to import a submodule relative to the caller? -

importing module can done in function, passed caller, take simple utility.

def import_reload_or_none(name, reload=true):     try:         mod = __import__(name)         if reload:             import importlib             mod = importlib.reload(mod)         return mod     except exception:         import traceback         traceback.print_exc()         return none 

this works root-level modules, i'm not sure how done when function in module or when relative imports used.

how function made work replace eg:

from . import my_package_module 

try passing path module want import function example:

def import_reload_or_none(name, reload=true, path=none):     mod = __import__(path + '/' + name) if path not none else __import__(name)     if reload:         import importlib         mod = importlib.reload(mod)     return mod 

then, if want import relative path can use

import_reload_or_none(my_package_module, path = '.')
