Question

我对此非常陌生并且一直在尝试使用此代码，但是当我使用它时，它会向我吐出这个错误

C:\Users\julia\Desktop\play>python play.py
QUESTION IS: Which of these film franchises has the most installments
OPTIONS ARE:
 ['Underworld', 'Resident Evil', 'Pirates of the Caribbean']
Analyzing...
Traceback (most recent call last):
  File "play.py", line 117, in <module>
    feed(img)
  File "play.py", line 95, in feed
    calculate_answer(question, answers)
  File "play.py", line 75, in calculate_answer
    ans_occ, = [x + y for x, y in zip(ans_occ, query_once(quest, ans))]
  File "play.py", line 52, in query_once
    content = get_response(query)
  File "play.py", line 40, in get_response
    req = urllib.request.Request(query, headers=headers)
  File "C:\Python36-32\lib\urllib\request.py", line 335, in __init__
    for key, value in headers.items():
AttributeError: 'tuple' object has no attribute 'items'

这是我从

有人可以告诉我这里需要改变什么吗？我对这种编码语言不是很有经验，所以请对我很轻松。我非常感激。

Answer 1

。 Items（）方法用于字典而不是元组

Answer 2

使用字典设置标题而不是元组，如下所示：

headers = {'User-Agent': 'Mozilla/5.0'}
