Python integer incrementing with ++ [duplicate]

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?

Solution 1:

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

number += 1

Solution 2:

Simply put, the ++ and -- operators don't exist in Python because they wouldn't be operators, they would have to be statements. All namespace modification in Python is a statement, for simplicity and consistency. That's one of the design decisions. And because integers are immutable, the only way to 'change' a variable is by reassigning it.

Fortunately we have wonderful tools for the use-cases of ++ and -- in other languages, like enumerate() and itertools.count().

Solution 3:

You can do:

number += 1
