列表中的重复元组

Question

我真的不知道我的代码中出现了什么错误，导致列表中有重复的元组，所以我可以在这方面获得一些帮助吗

因此，我使用google textsearch api搜索某个地方附近的餐馆，在将它们转换为json后，我得到了以下数据。

我试图从中提取每家餐厅的名称、地址、营业时间、价格水平和评级，并将它们转换为列表中的元组。因此，我编写了以下代码来执行此任务：

for container in l:
   for key, value in container.items():
      response_data.extend([(container.get('name'),container.get('formatted_address'),container.get('opening_hours'),container.get('price_level'),container.get('rating'))])

我用这段代码得到了正确的格式，但由于某种原因它复制了结果，我似乎找不到原因。结果是这样的：

有人能帮忙吗

谢谢

以下是“l”的示例：

Answer 1

您可以通过set实现这一点

thelist = list(set(thelist))

编辑： 有了字典，这将失败

>>> l = [(1, "foo"), (1, "foo"), (2, "bar")]
>>> list(set(l))
[(2, 'bar'), (1, 'foo')]

>>> l = [(1, "foo"), (1, "foo"), (2, "bar"), (3, {"open_now": False}), (4, {"open_now": True}), (3, {"open_now": False})]
>>> list(set(l))
TypeError: unhashable type: 'dict'

在这种情况下，您可以从元组中省略字典，或者将其转换为一个字符串，该字符串稍后可以转换回dict

Answer 2

如果你只运行了几次。如果时间不是那么重要的问题

你可以用

mylist = list(dict.fromkeys(mylist))

删除重复项

Answer 3

您可以使用以下代码来实现它，以使事情更清楚、更快地添加您希望在筛选字典时查找的一组关键字

In [9]: keys = {"name", "formatted_address", "opening_hours", "price_level", "rating"}

In [10]: [(key,value) for restaurant in l for key,value in restaurant.items() if key in keys]
Out[10]: 
[('formatted_address', '2893 Broadway, New York, NY 10025, United States'),
 ('name', 'Community Food & Juice'),
 ('opening_hours', {'open_now': False}),
 ('price_level', 2),
 ('rating', 4.3),
 ('formatted_address',
  '1172 Amsterdam Ave, New York, NY 10027, United States'),
 ('name', "Brownie's Cafe"),
 ('price_level', 1),
 ('rating', 4.6),
 ('formatted_address',
  '1239 Amsterdam Ave, New York, NY 10027, United States'),
 ('name', 'Massawa'),
 ('opening_hours', {'open_now': False}),
 ('price_level', 2),
 ('rating', 4.5)]
