I want to transfer a list of tuples:
[(1, 3, 5), (2, 4, 6), (7, 8, 9)]
to a list of dict
(in order to create a pandas dataframe) which looks like:
[{'index':1, 'match':1},{'index':1, 'match':3},{'index':1, 'match':5},
{'index':2, 'match':2}, {'index':2, 'match':4},{'index':2, 'match':6},
{'index':3, 'match':7},{'index':3, 'match':8},{'index':3, 'match':9}]
For performance reasons I wanted to use a list and dict comprehension:
[{'index':ind, 'match': } for ind, s in enumerate(test_set, 1)]
How can this be achieved?
You can use list comprehension use a second for
to loop over the 'match'
es:
[{'index':ind, 'match':} for ind,s in enumerate(test_set,1) ]
So the second for
loop iterates over the elements in the tuples and for each of these elements, a dictionary is generated and added to the result.
