Programmatically turn module/set of functions into a Python class

Question

Suppose I have a file with a bunch methods as bunch_methods.py:

def one(x):
  return int(x)

def two(y)
  return str(y)

Is there a way to take th

Answer 1

No idea why you want to do this, but a simple approach could be:

def to_class(module):
    class TheClass(object): pass
    for attr in dir(module):
        val = getattr(module, attr)
        if callable(val):
            setattr(TheClass, attr, staticmethod(val))
    return TheClass

Usage:

>>> import math
>>> Math = to_class(math)
>>> m = Math()
>>> m.sin(5)
-0.9589242746631385
>>> math.sin(5)
-0.9589242746631385
>>> Math.sin(5)
-0.9589242746631385

If the module has also some variables, you could enhance it to add non-callable objects to the class too:

def to_class(module):
    class TheClass(object): pass
    for attr in dir(module):
        val = getattr(module, attr)
        if callable(val):
            setattr(TheClass, attr, staticmethod(val))
        else:
            setattr(TheClass, attr, val)
    return TheClass

However doing more than this becomes really hard and ugly and you must have a really good reason for doing this, otherwise it's wasted effort.
