How to subtract continuously from a number

Beginner python user here. I'm writing some code for a basic attack in an rpg, and it looks like this:

import random
class attack:

    health = 300

    for i in range(1):
        if (random.uniform(0, 10)) <= int(8.2):
            health = health - 50
            print("Your attack hit.\n" + "The monster's health is at " + str(health))
        else:
            print("Your attack missed.\n" + "The monster's health is at " + str(health))

When the attack hits, this is what's printed:

Your attack hit.
The monster's health is at 250

I'm trying to continuously subtract from the heath until it goes down to zero. How do I write this so that 50 continuously subtracts from 300 whenever I run the program (instead of just staying at 250)?

It is better if you use a function, instead of a class, and you can use a while loop to keep on attacking into health is smaller then 0.

import random
def attack():
    health = 300
    while health > 0:
        if (random.uniform(0, 10)) <= int(8.2):
             health -= 50
             print("Your attack hit.\n" + "The monster's health is at " + str(health))
        else:
             print("Your attack missed.\n" + "The monster's health is at " + str(health))
attack()

Your loop is only executing once.

for i in range(1):

If you want it to run until health is 0, you'll need a while loop:

while health > 0:

You can use a while loop- it'll run until the condition's met (in this case, until health is 0):

while health > 0:
    if (random.uniform(0, 10)) <= int(8.2):
            health = health - 50
            print("Your attack hit.\n" + "The monster's health is at " + str(health))
        else:
            print("Your attack missed.\n" + "The monster's health is at " + str(health))

Use a while loop like

while health > 0:
    if (random.uniform(0, 10)) <= int(8.2):
        health = health - 50
        print("Your attack hit.\n" + "The monster's health is at " + str(health))
    else:
         print("Your attack missed.\n" + "The monster's health is at " + str(health))
