Actually, you don't need a "global foo" statement to _access_ the value. You do need a "global foo" to _rebind_ the value. > ... > > IIRC, for dictionaries you DO NOT have this issue? > > Why this scope problem with integers but not dictionaries? Telling an object to mutate itself doesn't rebind the object. so, if you wanted to say: foo = 5 and have it work at the module level, you'd need a global foo statement, while foo["bar"] = "spam" doesn't. The dictionary "foo" isn't rebound, all that's happening is that its state is being changed (that is, the key and value is being added to the dictionary).
