How do I operate on the actual object, not a copy, in a python for loop?

Question

let\'s say I have a list

a = [1,2,3]

I\'d like to increment every item of that list in place. I want to do something as syntactically easy

Answer 1

Instead of your map-based solution, here's a list-comprehension-based solution

a = [item + 1 for item in a]
