如何修复石头剪刀布程序中的循环和中断错误？

问：

我编写了一个基本程序，用于在 Powershell 中运行石头、纸张和剪刀布。

import random

print("Lets play Rock, Paper, Scissors...")
print("Type 'quit' to quit the game")
pwins = 0
cwins = 0
winning_score = 2

while pwins < winning_score and cwins < winning_score:
    print(f"Player wins:{pwins} | Computer wins: {cwins}")
    p1 = input("Player's move: ").lower()
    
    rand_num = random.randint(0,2)
    if rand_num == 0:
        computer = "rock"
    elif rand_num == 1:
        computer = "paper"
    else:
        computer = "scissors"

    if p1 == "quit" or p1 == "q":
        break
        
    print(f"Computer chooses: {computer}")

    if p1 == computer:
        print("It's a tie...")
        p1 = input("Player's move: ").lower()

    if p1 == "rock":
        if computer == "paper":
            print("Computer wins")
            cwins += 1
        else:
            print("Player wins")
            pwins += 1
    elif p1 == "paper":
        if computer == "scissors":
            print("Computer wins")
            cwins += 1
        else:
            print("Player wins")
            pwins += 1
    elif p1 == "scissors":
        if computer == "rock":
            print("Computer wins")
            cwins += 1
        else:
            print("Player wins")
            pwins += 1
    else:
        print("Please enter a valid move!")

    print(f"Final score... Player: {pwins} | Computer: {cwins}")

    if pwins > cwins:
        print("Congrats, you won!")
    elif pwins < cwins:
        replay = input("You lost...Do you want to play again? (y/n) ")
    if replay == "y":
        cwins = 0
        pwins = 0
    else:
        print("Loser!")
    else:
        print("It's a tie")`

问题在于每当我得到 p1 == 计算机领带时，如果我选择立即退出，我就会得到一个错误。我得到“请输入有效移动！”作为响应。如果我在第二次输入“退出”之后，程序将正确结束。

第二个问题是一旦玩家输了，程序会问“你想再玩一次吗？（是/否）”。如果我选择“y”，程序不会循环，只会结束。

我尝试移动代码部分并将它们按不同的顺序放置以使中断和循环正常运行，但我不知所措，因为问题不会得到解决并且会出现其他错误。感谢您的帮助。
