函数定义中出现意外缩进错误

Question

我有一个怪物在房间之间随机移动的代码，但全局值出现了意外的意图错误。

def monster(): """moves the monster randomly"""
global monster_current_room
if monster_current_room["name"] != current_room:
print('The monster is currently in', monster_current_room["name"])
exits = list(monster_current_room["exits"].values())
if random.randint(1, 4) == 4:
monster_current_room = rooms[random.choice(exits)]
elif monster_current_room["name"] == current_room:
game_over = True

如果我取消了全局值，它就充当了定义的末尾，并且希望在定义和全局值之间有两条线。当我尝试使用缩进运行时，程序失败并出现错误。

您放错了函数注释：

def monster(): 
"""
moves the monster randomly
"""
global monster_current_room
if monster_current_room["name"] != current_room:
print('The monster is currently in', monster_current_room["name"])
exits = list(monster_current_room["exits"].values())
if random.randint(1, 4) == 4:
monster_current_room = rooms[random.choice(exits)]
elif monster_current_room["name"] == current_room:
game_over = True

或者，如果你喜欢内联评论，你可以像一样

def monster(): # moves the monster randomly
global monster_current_room
if monster_current_room["name"] != current_room:
print('The monster is currently in', monster_current_room["name"])
exits = list(monster_current_room["exits"].values())
if random.randint(1, 4) == 4:
monster_current_room = rooms[random.choice(exits)]
elif monster_current_room["name"] == current_room:
game_over = True

当您编写像这样的多行字符串时

"""
moves the monster randomly
"""

它必须遵守python代码中经典语句的规则。所以你不能把它们放在任何你想点赞的地方。
