Here are some best practices when using augmented assignments in Python: Use whitespace around the operators: x += 1 rather than x+=1 for readability. Limit chaining augmented assignments like x = y = 0. Use temporary variables if needed for clarity. Don’t overuse augmented assignment especially with mutable types.Try: a[i] += 1. you are changing the value of i and that's not changing the elements of the list a . if you want to change the value of the elements of that list, you can do: element+=1. a[index] = element. You need to change the value of each element in a instead of the value of i because this is not changing the elements of a.Feb 21, 2024 · Why doesn’t the “++/--” operator work in Python?
