Convert module to dict

Question

I would like to do the following (python3):

In module settings.py:

message = 'Hello'

In module __main__.py:

from . import settings


def dict_from_module(module):
    ...
    return d

print(dict_from_module(settings))

Running this should produce:

{'message': 'hello'}

Is there a canonical way of converting a module to a dictionary?

EDIT

Using vars(settings) gives lots of internal information:

{   
    '__builtins__': {
        ...
    },
    '__cached__': 'xxx/__pycache__/settings.cpython-34.pyc',
    '__doc__': None,
    '__file__': 'xxx/settings.py',
    '__loader__': <_frozen_importlib.SourceFileLoader object at 0x7f87fc192518>,
    '__name__': 'xxx.settings',
    '__package__': 'xxx',
    '__spec__': ModuleSpec(...),
    'message': 'bye'
}

Which I do not want / need. I can filter that out (by removing keys starting with __), but I would like to avoid hacking around if there is an accepted way of doing this.

Hope this helps!

def dict_from_module(module):
    context = {}
    for setting in dir(module):
        # you can write your filter here
        if setting.islower() and setting.isalpha():
            context[setting] = getattr(module, setting)

    return context
