我将申请一个简短的代码。

注意：“湿度”后有类似“↑”的箭头，可以将其添加到单独的列中，称为（风向）。

这是Jupyter笔记本中的外观：

因此，您有一个Series，其中包含描述某天信息的字典列表。 Series是表的第二列。为了简单起见，我仅使用几行：

data = pd.Series([
[{'Time': '12:58 amMon, Feb 1', 'Temp': '50°F', 'Weather': 'Light rain. Mostly cloudy.', 'Wind': '13 mph', 'Humidity': '↑', 'Barometer': '88%', 'Visibility': '29.79 "Hg'},{'Time': '1:58 am', 'Temp': '46°F', 'Weather': 'Mostly cloudy.', 'Wind': '12 mph', 'Humidity': '↑', 'Barometer': '83%', 'Visibility': '29.82 "Hg'}],
[{'Time': '12:58 amWed, Feb 10', 'Temp': '17°F', 'Weather': 'Mostly cloudy.', 'Wind': '13 mph', 'Humidity': '↑', 'Barometer': '72%', 'Visibility': '29.91 "Hg'}, {'Time': '1:58 am', 'Temp': '15°F', 'Weather': 'Mostly cloudy.', 'Wind': '10 mph', 'Humidity': '↑', 'Barometer': '72%', 'Visibility': '29.91 "Hg'}]])

它看起来像：

0    [{'Time': '12:58 amMon, Feb 1', 'Temp': '50°F'...
1    [{'Time': '12:58 amWed, Feb 10', 'Temp': '17°F...

现在，我想将Series的字典列表展平为Series的字典：

from itertools import chain

flatten = list(chain.from_iterable(data))

然后构造结果数据框：

result = pd.DataFrame(flatten)

外观如下：

  Barometer Humidity  Temp   ...   Visibility                     Weather    Wind
0       88%        ↑  50°F   ...    29.79 "Hg  Light rain. Mostly cloudy.  13 mph
1       83%        ↑  46°F   ...    29.82 "Hg              Mostly cloudy.  12 mph
2       72%        ↑  17°F   ...    29.91 "Hg              Mostly cloudy.  13 mph
3       72%        ↑  15°F   ...    29.91 "Hg              Mostly cloudy.  10 mph

[4 rows x 7 columns]

对整个数据集执行相同的操作，并开心！
