Is this something like what you're looking for?
>>> def functionmaker():
... shared = []
... def addnumber():
... shared.append(3)
... return shared
... def addletter():
... shared.append('f')
... return shared
... return addnumber, addletter
...
>>> addnumber, addletter = functionmaker()
>>> addnumber()
[3]
>>> addletter()
[3, 'f']
