Python: thinking of a module and its variables as a singleton — Clean approach?

Question

I\'d like to implement some sort of singleton pattern in my Python program. I was thinking of doing it without using classes; that is, I\'d like to put all the singleton-rel

Building off of WillYang's answer and taking it a step further for cleanliness: define a simple class to hold your global dictionary to make it easier to reference:

class struct(dict):
    def __init__(self, **kwargs):
        dict.__init__(self, kwargs)
        self.__dict__ = self

g = struct(var1=None, var2=None)

def func():
    g.var1 = dict()
    g.var3 = 10
    g["var4"] = [1, 2]
    print(g["var3"])
    print(g.var4)

Just like before you put anything you want in g but now it's super clean. :)
