I’ve always laughed to myself when I’ve looked back at my VB6 days and
thought, “What modern language doesn’t allow incrementing with double plus
signs?”:

number++

To my surprise, I can’t find anything about this in the Python docs. Must I
really subject myself to number = number + 1? Don’t people use the ++/--
notation?


问题答案:

Python doesn’t support ++, but you can do:

number += 1
