Question

我是Python和编程的新手。我试图在夏季学期开始上大学。我试图从这本初学者的书中学习，它引用了下面的代码，正如我所说的那样...我试着改变空间缩进，但我仍然得到这个消息。我理解我可能在这里遗漏了一些东西，但我很欣赏有关如何继续的建议。

Python 3.6.3 (v3.6.3:2c5fed8, Oct  3 2017, 17:26:49) [MSC v.1900 32 bit (Intel)]


  >>> # Ghost Game
   ... from random import randint
   >>> print('Ghost Game')
   Ghost Game
   >>> feeling_brave = True
   >>> score = 0
   >>> while feeling_brave:
   ... ghost_door = randint(1, 3)
    File "<stdin>", line 2
    ghost_door = randint(1, 3)
             ^
   IndentationError: expected an indented block
    >>> ghost_door= randint(1, 3)
    >>> while feeling_brave:
    ... ghost_door= randint(1, 3)
    File "<stdin>", line 2
    ghost_door= randint(1, 3)
             ^
IndentationError: expected an indented block
>>> while feeling_brave:
... ghost_door = randint(1, 3)
  File "<stdin>", line 2
    ghost_door = randint(1, 3)
             ^
    IndentationError: expected an indented block
    >>> while feeling_brave:
    ... ghost_door = randint(1,3)
    File "<stdin>", line 2
       ghost_door = randint(1,3)
             ^
   IndentationError: expected an indented block
   >>> while feeling_brave:
   ... ghost_door =randint(1,3)
     File "<stdin>", line 2
    ghost_door =randint(1,3)

Answer 1

在“while”语句之后，口译员会显示“......”。您必须在下一行的开头键入四个空格来提供缩进。

Answer 2

按行

上现有缩进前面的[TAB]添加缩进

... ghost_door = randint(1,3)

目前，你有：

while feeling_brave:
    ghost_door = randint(1, 3)

你还没有得到＃34;陈述＆＃34;对于循环作为缩进，所以解释器将其视为两个连续的命令。但是，有

while feeling_brave:
    ghost_door = randint(1, 3)

告诉解释器在循环运行时执行第二行。

新的和坚持IndentationError：期望一个缩进块
