Python: How can I separate functions of class into multiple files?

Question

I know this has been asked a couple of times, but I couldn\'t quite understand the previous answers and/or I don\'t think the solution quite represents what I\'m shooting fo

Answer 1

I use the approach I found here It shows many different approaches, but if you scroll down to the end it the preferred method is to basically go the opposite direction of @Martin Pieter's suggestion which is have a base class that inherits other classes with your methods in those classes.

so folder structure something like:

_DataStore/
    __init__.py
    DataStore.py
    _DataStore.py

So your base class would be:

# DataStore.py

import _DataStore

class DataStore(_DataStore.Mixin): # Could inherit many more mixins

    def __init__(self):
        self._a = 1
        self._b = 2
        self._c = 3

    def small_method(self):
        return self._a

Then your Mixin class:

# _DataStore.py

class Mixin:

    def big_method(self):
        return self._b

    def huge_method(self):
        return self._c

Your separate methods would be located in other appropriately named files, in this example it is just _DataStore.

I am interested to hear what others think about this approach, I showed it to someone at work and they were scared by it, but it seemed to be a clean and easy way to separate a class into multiple files.
