Question

为什么我收到此属性错误？

class GameState(object):
  """Keeps track game state variables"""
  def __init__(self, convo_flag=0, characters_talked_to=0, convo_log=(None)):
    self.convo_flag = convo_flag
    self.characters_talked_to = characters_talked_to
    self.convo_log = convo_log

def welcome_screen():
  global LAST_NAME
  global BULLY
  global DAY

  raw_input(messages.WELCOME)

  LAST_NAME = raw_input(messages.LAST_NAME)
  BULLY = characters.random_character(cclass='Camper', gender='m')

  print 'Your name is Pickett %s' % LAST_NAME

  messages.print_messages([
    messages.EXPLANATION,
    messages.BUS_LOADING,
    messages.CRACK,
    messages.GAME_KID_LOST])

  return week_one(DAY)

def week_one(day):
  if day == 1:
    messages.print_messages(messages.WEEK_ONE[day])
    campers = characters.random_character_sample(cclass='Camper', count=5)
    people_outside_theater = campers + [characters.TROID]

    while GameState.characters_talked_to != 3:

我不知道为什么我得到这个属性错误，我完全在那个构造函数中声明它，是否有一些我缺少的是我需要在构造函数之外声明它？这真的是我的大脑。

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "pickett.py", line 44, in welcome_screen
    return week_one(DAY)
  File "pickett.py", line 52, in week_one
    while GameState.characters_talked_to != 3:
AttributeError: type object 'GameState' has no attribute 'characters_talked_to'

Answer 1

您需要创建一个实例，以便您像这样使用您的类：

gameState = GameState()
while gameState.characters_talked_to != 3:

在您的代码中，您尝试访问未在班级中定义的class-level attribute。

Answer 2

__init__个characters_talked_to函数设置了self GameState GameState的实例{/ 1}}。

您没有在GameState上设置它，这是一个类。

您也没有创建__init__的任何实例，因此在任何情况下{{1}}都不会被您的程序调用。

类属性显然存在，但是python无法找到它
