如何在python中將串列轉換為字典？[復制]

我有一個這樣的清單。包含問題及其答案。

list=[['It has been noted that in __________________ urban cities quickly expanded rather than the slow evolution of urbanism in the northwest.',
      'Gujarat'],
     ['These traditions and cultures include Anarta Tradition c. 39501900 BC Padri Ware 36002000 BC PrePrabhas Assemblage 32002600 BC Pre Urban Harappan Sindh __________________ Pottery Burial Pottery 30002600 BC Black and Red Ware 3950900 BC Reserved Slip Ware 39501900 BC Micaceous Red Ware 26001600 BC.',
      'Type'],
     ['Later in the 18th century Gujarat came under control of the __________________ Empire who dominated the politics of India.',
      'Maratha']]

我想轉換成給定的形式。

output =[{'question': 'It has been noted that in __________________ urban cities quickly expanded rather than the slow evolution of urbanism in the northwest.','answer':'Gujarat'}, {'question': 'These traditions and cultures include Anarta Tradition c. 39501900 BC Padri Ware 36002000 BC PrePrabhas Assemblage 32002600 BC Pre Urban Harappan Sindh __________________ Pottery Burial Pottery 30002600 BC Black and Red Ware 3950900 BC Reserved Slip Ware 39501900 BC Micaceous Red Ware 26001600 BC.','answer':'Type'}, {'question': 'Later in the 18th century Gujarat came under control of the __________________ Empire who dominated the politics of India.','answer':'Maratha'}

可能嗎 ？如果是，那么如何？

串列理解就足夠了：

[{'question': q, 'answer': a} for q, a in list]

這輸出：

[{'question': 'It has been noted that in __________________ urban cities '
              'quickly expanded rather than the slow evolution of urbanism in '
              'the northwest.',
  'answer': 'Gujarat'},
 {'question': 'These traditions and cultures include Anarta Tradition c. '
              '39501900 BC Padri Ware 36002000 BC PrePrabhas Assemblage '
              '32002600 BC Pre Urban Harappan Sindh __________________ Pottery '
              'Burial Pottery 30002600 BC Black and Red Ware 3950900 BC '
              'Reserved Slip Ware 39501900 BC Micaceous Red Ware 26001600 BC.',
  'answer': 'Type'},
 {'question': 'Later in the 18th century Gujarat came under control of the '
              '__________________ Empire who dominated the politics of India.',
  'answer': 'Maratha'}]

你可以試試這個：（考慮不要使用內置函式作為變數。list 是一個內置函式。）

# >>> lst = list
>>> [{'question': l[0], 'answer': l[1]} for l in lst]

[{'question': 'It has been noted that in __________________ urban cities quickly expanded rather than the slow evolution of urbanism in the northwest.',
  'answer': 'Gujarat'},
 {'question': 'These traditions and cultures include Anarta Tradition c. 39501900 BC Padri Ware 36002000 BC PrePrabhas Assemblage 32002600 BC Pre Urban Harappan Sindh __________________ Pottery Burial Pottery 30002600 BC Black and Red Ware 3950900 BC Reserved Slip Ware 39501900 BC Micaceous Red Ware 26001600 BC.',
  'answer': 'Type'},
 {'question': 'Later in the 18th century Gujarat came under control of the __________________ Empire who dominated the politics of India.',
  'answer': 'Maratha'}]

添加以下行，然后您將獲得所需的輸出：

新串列 = []

對于串列中的資料：

# data[0] contains first element and data[1] contains second element.

dict = {'question': data[0], 'answer': data[1]}  
new_list.append(dict)

只需創建一個新串列并附加問題和答案的資料字典。

可以這樣做：

my_list = [['It has been noted that in __________________ urban cities quickly expanded rather than the slow evolution of urbanism in the northwest.',
  'Gujarat'],
 ['These traditions and cultures include Anarta Tradition c. 39501900 BC Padri Ware 36002000 BC PrePrabhas Assemblage 32002600 BC Pre Urban Harappan Sindh __________________ Pottery Burial Pottery 30002600 BC Black and Red Ware 3950900 BC Reserved Slip Ware 39501900 BC Micaceous Red Ware 26001600 BC.',
  'Type'],
 ['Later in the 18th century Gujarat came under control of the __________________ Empire who dominated the politics of India.',
  'Maratha']]
output = [{'question': item[0], 'answer': item[1]} for item in my_list]

提示：不要命名與 python 內置資料型別（如串列、集合等）沖突的變數，因為它可能會產生不良后果
