How to add one point to a variable every 100 messages?

Question

Python

Hello, I would like to make some kind of "reward system" for an asset in a conversation. So that for example every 100 messages one number is added to the "points" variable.
I'm not interested in the message count, but how to do something every 100 messages.
Here is the script that counts the messages:

if event.type == VkBotEventType.MESSAGE_NEW:
    messages = messages + 1

Answer 1

for event in longpoll.listen():
    if event.type == VkBotEventType.MESSAGE_NEW:
        for a in range(0, 100):
            if a >= 100:
                #Действие
