passing pointer as argument to function in py

I have 2 function that use the same variable, like this:

some_function():
    #do something with MyDict
    MyDict = dict()
    MyDict['name'] = 'hallo'

main():
    #do something else with MyDict
    MyDict['age'] = 33
    some_function()

I don't want to use global and let say that MyDict is very big and I don't want to pass it to some_function. what is the best way to do so? there is a way to pass a pointer to MyDict? PS: I'm using py3.2

In short: when you pass a dict as argument to a function, only the reference is passed, the data is not copied.

However, in general the parameters are references but some types are mutables but others aren't which changes the behavior.
