列表中的重复元组
Duplicated tuple within a list
我能得到一些帮助吗，因为我真的不知道我的代码出了什么问题导致列表有重复的元组。
所以我使用google文本搜索api搜索某个地方附近的餐馆，将它们转换为json后得到以下数据。
我正在尝试从那里提取每家餐厅的名称、formatted_address、opening_hours、price_level 和评级，并将它们转换为列表中的元组。所以我写了下面的代码来执行这个工作：
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，但由于某种原因它重复了结果，我似乎找不到原因。结果如下：
任何人都可以帮忙吗？
谢谢！

如果你是 运行 这只有几次。如果时间不是什么大问题。
你可以直接使用，
mylist = list(dict.fromkeys(mylist))
删除重复项。
您可以通过 set 实现。
thelist = list(set(thelist))
编辑：
使用字典这将失败。
>>> 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，稍后可以将其转换回 dict。
尝试 this:you 数据重复，因为你的第二个 loop.you 实际上并不需要它。
response_data = []
for container in l:
response_data.append((container.get('name'),container.get('formatted_address'),container.get('opening_hours'),container.get('price_level'),container.get('rating')))
您可以使用以下代码实现它，使事情变得更清楚、更快速，将您希望检查的键添加到您在过滤字典时查找的集合中。
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]
