python - 如何将字典列表写入具有多个值的 CSV

Question

我在“my_list”中有一个字典列表，如下所示:

my_list=[{'Id': '100', 'A': [val1, val2], 'B': [val3, val4], 'C': [val5,val6]}, 
         {'Id': '200', 'A': [val7, val8], 'B': [val9, val10], 'C': 
         [val11,val12],
         {'Id': '300', 'A': [val13, val14], 'B': [val15, val16], 'C':   
         [val17,val18]}]

我想将此列表写入 CSV 文件，如下所示:

ID,  A,     AA,    B,     BB,    C,     CC
100, val1,  val2,  val3,  val4,  val5,  val6
200, val7,  val8,  val9,  val10, val11, val12
300, val13, val14, val15, val16, val17, val18   

有谁知道我该如何处理吗？

Tablib应该可以解决问题

我将示例保留在他们的首页上(您可以调整为 .csv 格式):

>>> data = tablib.Dataset(headers=['First Name', 'Last Name', 'Age'])
>>> for i in [('Kenneth', 'Reitz', 22), ('Bessie', 'Monke', 21)]:
...     data.append(i)


>>> print(data.export('json'))
[{"Last Name": "Reitz", "First Name": "Kenneth", "Age": 22}, {"Last Name": "Monke", "First Name": "Bessie", "Age": 21}]

>>> print(data.export('yaml'))
- {Age: 22, First Name: Kenneth, Last Name: Reitz}
- {Age: 21, First Name: Bessie, Last Name: Monke}

>>> data.export('xlsx')
<censored binary data>

>>> data.export('df')
  First Name Last Name  Age
0    Kenneth     Reitz   22
1     Bessie     Monke   21
