python - apply Operation on multiple variables

Question

I know that this is a rather silly question and there are similar ones already answered, but they don\'t quite fit, so... How can I perform the same operation on multiple variab

Answer 1

Map is your friend here, but you also need to use 'implicit tuple unpacking':

>>> a = 3
>>> b = 4
>>> c = 5
>>> d, e, f = map(lambda x: x * 2, [a, b, c])
>>> d
6
>>> e
8
>>> f
10

This way you can get the changed values back without modifying the original values
