Python: How to import all methods and attributes from a module dynamically

If you have your module object, you can mimic the logic import * uses as follows:

module_dict = my_module.__dict__
try:
    to_import = my_module.__all__
except AttributeError:
    to_import = [name for name in module_dict if not name.startswith('_')]
globals().update({name: module_dict[name] for name in to_import})

However, this is almost certainly a really bad idea. You will unceremoniously stomp on any existing variables with the same names. This is bad enough when you do from blah import * normally, but when you do it dynamically there is even more uncertainty about what names might collide. You are better off just importing my_module and then accessing what you need from it using regular attribute access (e.g., my_module.someAttr), or getattr if you need to access its attributes dynamically.

Not answering precisely the question as worded, but if you wish to have a file as proxy to a dynamic module, you can use the ability to define __getattr__ on the module level.

import importlib
import os

module_name = os.environ.get('CONFIG_MODULE', 'configs.config_local')
mod = importlib.import_module(module_name)

def __getattr__(name):
    return getattr(mod, name)
