找不到语法错误[关闭]

我正在编写一个简单的基于文本的角色扮演游戏，我正在尝试让库存系统正常工作。我已经逐字复制了工作代码，但出现语法错误。我不确定我做错了什么，因为它对我来说看起来很好。抱歉新手问题。谢谢你！

class Container(object):

        def__init__(self, name):
                self.name = name
                self.inside = {}

    def__iter__(self):
            return iter(self.inside.items())

    def__len__(self):
            return len(self.inside)

    def__contains__(self, item):
            return item.raw in self.inside

    def__getitem__(self, item):
            return self.inside[item.raw]

    def__setitem__(self, item, value):
            self.inside[item.raw] = value
            return self[item]

    def add (self, item, quantity=1):
            if quantity < 0:
                    raise ValueError("Negative quantity.  Use remove() instead.")

            if item in self:
                    self[item].quantity += quantity
                    self[item].recalc()

            else:
                    self[item].quantity -= quantity
                    self[item].recalc()

当我运行它时出现以下错误：

Traceback (most recent call last):
  File "game.py", line 2, in <module>
    from characters.player import *
  File "/home/dave/Projects/rpg-master/characters/player.py", line 4, in <module>
    from items.container import *
  File "/home/dave/Projects/rpg-master/items/container.py", line 4
    def__init__(self, name):
                           ^
SyntaxError: invalid syntax

非常感谢您的帮助。

后面没有空格def:

def__init__(self, name):
    self.name = name
    self.inside = {}

应该

def __init__(self, name):
    self.name = name
    self.inside = {}

对于其余的类函数，依此类推。
