在 python 中设置 integer 后，while 或循环未停止

Question

Trying to make a rock paper scissor game with a player versing the computer to refresh knowledge on coding however I can't seem to find what's causing the issue in my while loop. I have it set to finish when either the computer or person reaches a score of 3 but stops whenever the total scores equal 8. Full code is listed below

import random

rock = "rock"
paper = "paper"
scissors = "scissors"
humanscore = int(0)
compscore = int(0)
limit = int(3)

comp = ["paper", "rock", "scissors"]

while humanscore <= limit or compscore <= limit:

human = str(input("Choose rock, paper, or scissors, first to 3 wins! "))
answer = random.choice(comp)

if human == answer:
    print("Tie, Computer chose, ", answer)

if answer == rock:
    if human == paper:
        humanscore += 1
        print("You Win!")
    elif human == scissors:
        compscore += 1
        print("Computer Won! Try again")

if answer == paper:
    if human == rock:
        compscore += 1
        print("Computer Won! Try again")
    elif human == scissors:
        humanscore + 1
        print("You Win!")

if answer == scissors:
    if human == paper:
        compscore += 1
        print("Computer Won! Try again")
    elif human == rock:
        humanscore += 1
        print("You Win!")

print("\n Computer Chose: ", answer, "computer score: ", compscore, "Human Score:", humanscore)

Answer 1

As already said in comments, the problem is with the or in your break condition. As long as one of the scores is below or equal 3, it keeps running.

For instance, if humanscore = 3 and comp score = 2, both parts of the condition are true meaning it continues.

As soon as humanscore = 4 and compscore = 4, both humanscore <= 3 and compscore <= 3 evaluate to false, meaning it stops => total score is 8.

Hence, the while should be like follows (also it should be < instead of <= , because you want to stop as soon as one has 3 points):

while humanscore < limit and compscore < limit:

Answer 2

Once you've sorted out the loop - which if you only want to keep going while the scores are both below limit is corrected as per schilli's answer - you might like to consider a data structure suggestion:

Make a dict that records what choice beats a given choice:

whatBeats = {rock:paper, paper:scissors, scissors:rock}

# then later after choices are made...

if answer == whatBeats[human]:
    # computer win
elif human == whatBeats[answer]:
    # human win
else: 
    # draw

(Many decades ago I wrote a sorting program before I had learned about any indexed structure - like arrays - and your current method puts me in mind of that sort of effort).
