input

list=[['What did the Vedas contain large collections of?'], ['What did the Vedas contain large collections of?'], `['What was accompanied by the rise of ascetic movements in Greater Magadha?'], ['In what part of India did Wootz steel originate?'], ['What country was ruled by dynasties during the Classical period?']]`

output

dict=[{"question":"What did the Vedas contain large collections of?"},{"question":"What did the Vedas contain large collections of?"},{"question":"What was accompanied by the rise of ascetic movements in Greater Magadha?"}]

I have a 2D list. then how to convert it into a dict as shown in example?

CodePudding user response：

Just traverse the list, create a dictionary for each element and append them to the new variable d:

l=[['What did the Vedas contain large collections of?'], ['What did the Vedas contain large collections of?'], ['What was accompanied by the rise of ascetic movements in Greater Magadha?'], ['In what part of India did Wootz steel originate?'], ['What country was ruled by dynasties during the Classical period?']]
d = []

for i in l:
    d.append({"question":i[0]})
print(d)

Output:

[{'question': 'What did the Vedas contain large collections of?'}, {'question': 'What did the Vedas contain large collections of?'}, {'question': 'What was accompanied by the rise of ascetic movements in Greater Magadha?'}, {'question': 'In what part of India did Wootz steel originate?'}, {'question': 'What country was ruled by dynasties during the Classical period?'}]

CodePudding user response：

res = [{'question': x[0]} for x in list]

In Your example in output You have list again. But in any case you can use this code:

mydict = [{"question":e[0]} for e in mylist]

PS I'm renamed your vars named list, dict to mylist, mydict because it's not so good practice to use class names from standard lib for local vars.
