Question

If I were to use a class in a module how would I make it “top level” in it’s instance?

Structure:

/package
    __init__.py
    /subPackage
        __init__.py
        module.py
        subModule.py
    /theScript.py

python theScript.py

Source of theScript:

import package.subPackage.module
package.subPackage.module.method()

Source of /package/subPackage/module.py:

class module:
    def method(self): pass
moduleInstance = module()

I guess what I am asking is how would I make it so that I don’t have to do package.subPackage.module.moduleInstance.method() and could package.subPackage.module.method()

I know I can just remove the class and instance but I prefer the class because it makes it easier to subclass later if somebody wants to without needing to modify our source directly but if I ultimately have to I will just use methods instead of class/method in module.

Here is how the random module in the standard lib solved this problem:

_inst = Random()
seed = _inst.seed
random = _inst.random
uniform = _inst.uniform
triangular = _inst.triangular
...

Seems a reasonable solution to me. Of course there is the drawback that you have to manually keep the method lists in sync, but the worst thing that will happen if you forget to add a method name is an error message that tells you exactly what is missing.
