Adding 1 to range while doing loop

Question

So im trying to make a small game, but when i try to add one more to the loop, it dosent continue the loop. Is there any other way I could do this?

import random

chosenCard = 2

correctCard = 2


remove = random.randint(1, 3)
print(remove)

loop = 1

for i in range(loop):
    if remove == correctCard or remove == chosenCard:
        loop += 1
        print("remove == correctCard or remove == chosenCard --- Adding loop +1", loop)



print("Chosen", chosenCard)
print("Correct", correctCard)
print("remove", remove)

Once the range is evaluated it returns a range object from 0 to loop at the moment of evaluation. Changing the value of loop afterwards doesn't affect the range object... You might be better using a while loop instead... — Tomerikoo

You should use a while loop.

while loop > 0:
    if remove == correctCard or remove == chosenCard:
        loop += 1
        print("remove == correctCard or remove == chosenCard --- Adding loop +1", loop)
    loop -= 1

This does not work, because, changing a variable does not change an object created with it. Say you are in the shop and your wife wrote you a shopping list with 2 apples. If your wife then remembers that her mother comes for a visit, she can think that she needs 3 apples, but that does not change the number on your shopping list. The same is the case in your code. At the time the range is created, loop has a value of 1. So the range is created with 1 value. Later changing loop does not automatically change the range object. A while loop would be appropriate here:

import random

chosenCard = 2
correctCard = 2
remove = random.randint(1, 3)
loop = 1

while loop > 0
    if remove == correctCard or remove == chosenCard:
        loop += 1
        print("remove == correctCard or remove == chosenCard - Adding loop +1", loop)
    loop -= 1

print("Chosen :", chosenCard)
print("Correct :", correctCard)
print("Remove :", remove)
