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

Answer 1

Maybe you can put all the variables in a global dict, and you can directly use the dict in your functions without "global".

# Singleton-related variables
my_globals = {'foo': 'blah', 'bar':'stuff'}

# Functions that process the above variables
def work(some_parameter):
    if some_parameter:
        my_globals['bar'] = ...
    else:
        my_globals['foo'] = ...

why you can do it like this is Python Scopes and Namespaces.
