意外的取消缩进和语法错误答案

【问题描述】：

我对编程还很陌生，并且已经开始编写基于文本的游戏。

但是，我不断遇到两个错误；意外的取消缩进和语法错误。

我正在使用try，但它告诉我except 上的语法错误，如果我在except 之后删除整个块，它会在下一行给我一个“Unexpected Unndent”错误（在“左门”），突出显示空白。

def prompt_chouseroom1():
    prompt_2 = raw_input ("You know what to do by now:            ")
    try:
        if prompt_2 == ("Look around the room"):
            print ("You see two doors; one on the left, and one on the right. There is also a dead body in the middle of the room")
            print promt_chouseroom1 ()
        if prompt_2 == ("Go through left door"):
            left_door()
        if prompt_2 == ("Go through middle door"):
            prinnt ("WHAT?! You walked through the wall!")
            middle_door()
        if prompt_2 == ("Go through right door"):
            right_door()
        if prompt_2 == ("Look under the rug"):
            print ("Oh my... you... you weren't supposed to find that. Well... looks like you can leave already. You win. Congrats... I guess :( ")
            win_game()
        else:
            print ("Try to LOOK AROUNF THE ROOM.... just a hint ;)")
            print
            prompt_chouseroom1()
        except ValueError:
            print ("Try to LOOK AROUNF THE ROOM.... just a hint ;)")
            print
            prompt_chouseroom1()
def left_door():

【问题讨论】：

查看try的缩进。查看except 的缩进。这些行的缩进看起来有什么问题吗？

您捕获异常的行需要缩进与您的尝试相同的级别

try:
    if prompt_2 == ("Look around the room"):
        print ("You see two doors; one on the left, and one on the right. There is also a dead body in the middle of the room")
        print promt_chouseroom1 ()
    if prompt_2 == ("Go through left door"):
        left_door()
    if prompt_2 == ("Go through middle door"):
        prinnt ("WHAT?! You walked through the wall!")
        middle_door()
    if prompt_2 == ("Go through right door"):
        right_door()
    if prompt_2 == ("Look under the rug"):
        print ("Oh my... you... you weren't supposed to find that. Well... looks like you can leave already. You win. Congrats... I guess :( ")
        win_game()
    else:
        print ("Try to LOOK AROUND THE ROOM.... just a hint ;)")
        print
        prompt_chouseroom1()
except ValueError:
    print ("Try to LOOK AROUND THE ROOM.... just a hint ;)")
    print
    prompt_chouseroom1()

【解决方案2】：

你看到try: 是如何缩进的吗？您需要与except: 匹配相同的缩进级别这里的代码是固定的

def prompt_chouseroom1():
prompt_2 = raw_input ("You know what to do by now: ")
try:
    if prompt_2 == ("Look around the room"):
        print ("You see two doors; one on the left, and one on the right. There is also a dead body in the middle of the room")
        print promt_chouseroom1 ()
    if prompt_2 == ("Go through left door"):
        left_door()
    if prompt_2 == ("Go through middle door"):
        print ("WHAT?! You walked through the wall!")
        middle_door()
    if prompt_2 == ("Go through right door"):
        right_door()
    if prompt_2 == ("Look under the rug"):
        print ("Oh my... you... you weren't supposed to find that. Well... looks like you can leave already. You win. Congrats... I guess :( ")
        win_game()
    else:
        print ("Try to LOOK AROUNF THE ROOM.... just a hint ;)")
        print
        prompt_chouseroom1()
except ValueError:
        print ("Try to LOOK AROUNF THE ROOM.... just a hint ;)")
        print
        prompt_chouseroom1()
def left_door():
    return

另外，我不会使用 Try 和 except 来运行脚本。我会使用函数，然后再调用函数。

您会在我添加的代码末尾看到返回。这只是为了在我运行程序时没有出错。你可以删除它。
