开发Python老虎机游戏遇金额无法持久化保存问题求助

你的核心问题是每次用户选择重新玩时，递归调用了main()函数，这会让函数重新执行所有初始化代码，包括Money = 100，导致之前的余额被重置。另外代码里的Roll()函数没有实现，运行会报错，也需要补上。

修复后的完整代码 #

# Slot machine
import random
import time

def Roll(SlotMachine, Slot1, Slot2, Slot3):
    # 清空之前的结果
    Slot1.clear()
    Slot2.clear()
    Slot3.clear()
    # 模拟老虎机滚动
    for _ in range(3):
        Slot1.append(random.choice(SlotMachine))
        Slot2.append(random.choice(SlotMachine))
        Slot3.append(random.choice(SlotMachine))
    # 打印滚动结果
    print(f"[{Slot1[0]}] [{Slot2[0]}] [{Slot3[0]}]")

def main():
    # 初始金额只初始化一次
    Money = 100
    SlotMachine = ["Strawberry", "Apple", "Banana"]
    Slot1 = []
    Slot2 = []
    Slot3 = []
    
    play_again = True
    while play_again and Money > 0:
        print("If you lose, you'll lose all the money you put on the line. But if you win your money gets tripled!")
        MoneyOnTheLine = int(input("How much money would you like to put on the table? "))
        
        if MoneyOnTheLine < 0:
            print("Invalid amount, try again.")
            continue
        if MoneyOnTheLine > Money:
            print("You don't have that kind of money...")
            continue
        
        Money -= MoneyOnTheLine
        Roll(SlotMachine, Slot1, Slot2, Slot3)
        
        if Slot1 == Slot2 == Slot3:
            print("You win!")
            WinnersMoney = MoneyOnTheLine * 3
            print(f"You received {WinnersMoney}!")
            Money += WinnersMoney
            print(f"You have {Money} now!")
            Restart = input("Good job, you won! Wanna play again? (Yes/No) ").lower()
        else:
            print(f"You have {Money} now!")
            Restart = input("It seems you lost, wanna play again? (Yes/No) ").lower()
        
        # 根据用户选择设置是否继续，不再递归调用main()
        if Restart != "yes":
            play_again = False
            print("I'll see you another time, friend!")
    
    if Money <= 0:
        print("You are poor!")

if __name__ == "__main__":
    main()

关键修改说明 #

• 移除了递归调用main()的逻辑，改用play_again标志位控制循环，确保Money不会被重新初始化
• 实现了Roll()函数，完成老虎机滚动的核心逻辑，传入需要操作的列表参数
• 优化了输入校验的提示信息，让用户更清楚错误原因
• 调整了字符串格式化，用更简洁的f-string语法
• 添加了if __name__ == "__main__":规范，符合Python代码最佳实践

这样修改后，用户每次选择继续玩时，余额会被保留，不会重置为初始的100。
