Actually, while Python variables are not first-class objects, one could see them as dictionary-key pairs. So you can even pass them by reference by passing the dictionary and the key.
Well, you could pass them that way, but not necessarily change them: --> def func1(): ... a = 1 ... b = 2 ... swap(locals(), 'a', 'b') ... print a ... print b ... --> def swap(d, key1, key2): ... print d[key1], d[key2] ... d[key1], d[key2] = d[key2], d[key1] ... print d[key1], d[key2] ... --> func1() 1 2 2 1 1 2 -- ~Ethan~ -- https://mail.python.org/mailman/listinfo/python-list
