Python元组问题

我是python新手，据我所知，我收到了这个元组错误：

Traceback (most recent call last):
  File "/home/cambria/Main.py", line 10, in <module>
    main()
  File "/home/cambria/Main.py", line 5, in main
    respons3 = api.get_summoner_by_name('hi im gosan')
  File "/home/cambria/RiotAPI.py", line 31, in get_summoner_by_name
    return self._request(api_url)
  File "/home/cambria/RiotAPI.py", line 12, in _request
    for key, value in params.items():
AttributeError: 'tuple' object has no attribute 'items'

这是我收到的唯一一个我真的不太了解的错误。这是因为我的参数上没有

.items

？还是我把它初始化为一个空字典

编辑1：我尝试过修补元组和项目的东西，但没有任何运气，我的错误消息如下

Traceback (most recent call last):
  File "/home/cambria/Desktop/api/Main.py", line 10, in <module>
    main()
  File "/home/cambria/Desktop/api/Main.py", line 5, in main
    respons3 = api.get_summoner_by_name('hi im gosan')
  File "/home/cambria/Desktop/api/RiotAPI.py", line 33, in get_summoner_by_name
    return self._request(api_url)
  File "/home/cambria/Desktop/api/RiotAPI.py", line 23, in _request
    params=args
  File "/home/cambria/.local/lib/python2.7/site-packages/requests/api.py", line 69, in get
    return request('get', url, params=params, **kwargs)
  File "/home/cambria/.local/lib/python2.7/site-packages/requests/api.py", line 50, in request
    response = session.request(method=method, url=url, **kwargs)
  File "/home/cambria/.local/lib/python2.7/site-packages/requests/sessions.py", line 465, in request
    resp = self.send(prep, **send_kwargs)
  File "/home/cambria/.local/lib/python2.7/site-packages/requests/sessions.py", line 573, in send
    r = adapter.send(request, **kwargs)
  File "/home/cambria/.local/lib/python2.7/site-packages/requests/adapters.py", line 415, in send
    raise ConnectionError(err, request=request)
ConnectionError: ('Connection aborted.', gaierror(-2, 'Name or service not known'))

您的代码要求

params

为dict

{}

（或具有

.items

方法）。您传递了一个元组

（）

。两者并不等同

默认情况下，将

params

设置为

None

，并在需要时传递a

def _request(self, api_url, params=None):
    params = params if params is not None else {}
    ...

或者期望一个元组列表，而不是一个dict

def _request(self, api_url, params=()):
    for key, value in params:
    ...

元组

（）

没有名为

items

的方法。你可能把它错当成字典了。按如下方式更改您的代码：

def _request(self, api_url, params=None):
    if params is None:
        params = {}
    ...

您好，很抱歉回复太晚，昨晚发了这么晚。我试图修改你的答案，但我运气不好，收到了一条巨大的错误消息，我将在我的操作编辑1中发布。既然没有方法，你会删除.items（）吗？但是当我这样做的时候，我只是得到了我在OP中列出的这个请求错误

def _request(self, api_url, params=()):
    for key, value in params:
    ...

def _request(self, api_url, params=None):
    if params is None:
        params = {}
    ...
