Question

目标：

如果用户前两次键入“ right”，笑脸就会变得悲伤，因为它无法走出森林。
如果用户在第3次，第4次，第5次等上键入“ right”，笑脸就会变得沮丧，砍伐一些树木，制作桌子并将其翻转过来。
如果用户键入其他任何内容，则会向用户显示一条消息，提示“输入无效”。并要求再次输入。
如果用户键入“ left”，笑脸就会离开森林，程序终止。

Python代码：

n = input("You are in the Lost Forest\n****************\n****************\n :)\n****************\n****************\nGo left or right? ")
i = 1
while (n.lower() == "right"):
    if i < 3:    
        n = input("You are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? ")
    elif i >= 3:
        n = input("You are in the Lost Forest\n****************\n******       ***\n  (╯°□°）╯︵ ┻━┻\n****************\n****************\nGo left or right? ")
    i = i + 1    
while (n.lower() != "right") and (n.lower() != "left"):
    n = input("Invalid Input\nYou are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? ")    
while (n.lower() == "left"):
    print("\nYou got out of the Lost Forest!\n\o/")
    break

错误：

如果用户前两次键入“ right”或“ left”以外的任何内容，然后键入“ right”，则程序将立即终止，而没有机会键入“ left”。

我应该如何编辑代码？

更多类似内容：

lost = "You are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? "
inp = lost
rightCount = 0
while True:
    n = input(inp)
    if (n.lower() == "right"):
        rightCount = rightCount + 1
        if rightCount > 3:
            inp = ("You are in the Lost Forest\n****************\n******       ***\n  (╯°□°）╯︵ ┻━┻\n****************\n****************\nGo left or right? ")
        else:
           inp = lost  
    elif n.lower() == "left":
        print("\nYou got out of the Lost Forest!\n\o/")    #syntax error fixed
        break
    else:
        inp = ("Invalid Input\nYou are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? ")

Answer 2

我想您忘记了将所有内容包装到while True循环（或其他无穷循环）中。

是您需要的吗？

while True:
    n = input("You are in the Lost Forest\n****************\n****************\n :)\n****************\n****************\nGo left or right? ")
    i = 1
    if (n.lower() == "right"):
        if i < 3:    
            n = input("You are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? ")
        elif i >= 3:
            n = input("You are in the Lost Forest\n****************\n******       ***\n  (╯°□°）╯︵ ┻━┻\n****************\n****************\nGo left or right? ")
        i = i + 1    
    if (n.lower() != "right") and (n.lower() != "left"):
        n = input("Invalid Input\nYou are in the Lost Forest\n****************\n****************\n :(\n****************\n****************\nGo left or right? ")    
    if (n.lower() == "left"):
        print("\nYou got out of the Lost Forest!\n\o/")
        break

在Python的另一个循环中包装一个循环？
