--, Do ++

++ is not operator. It's just a combination of two + operator. As you know, there is no point in putting + in front of the int type variable.

in other words ++a = +(+a) = a This is.

If you want to calculate ++ and -- of C, Python requires +=1 and -=1.

Python is a language that values consistency and readability. This is not Python because ++ and -- can produce different results depending on the potential/post.

In addition, theoretically, ++ and -- operations are faster These days, the compiler optimizes the code on its own, so I don't think you need to pay much attention to the performance.
