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().

July 13, 2023Python doesn't allow to increment global variable inside function?
x += 1 is the same as x = x + 1. Functions cannot assign to global scope variables (without the global keyword), and they cannot mix local and global in the same function. In order to increment x, it has to already exist. When a function is defined, it stores internally all the local variables it is expecting to encounter. Python sees the assignment operator being used, so it will assume x is local. More on reddit.com

December 1, 2023 - >>> counter {'m': 1, 'i': 4, 's': 4, 'p': 2} The for loop iterates over the letters in word. In each iteration, the conditional statement checks if the letter at hand isn’t already a key in the dictionary you’re using as counter. If so, it creates a new key with the letter and initializes its count to zero. The final step is to increment the count by one.
