Python - List comprehension with multiple arguments in the for

Question

I have this current list comprehension:

...
cur = [[14, k, j] for j, k in rows[14], range(15)]
...

and it is giving me the following error:

...        
    cur = [[14, k, j] for j, k in rows[14], range(15)]
ValueError: too many values to unpack

Any help appreciated as in how I would fix this. I just don't want to have to write out a full for loop or the entire list by hand. Thank you! :D

Extra info:

rows = [{1: '75'},
        {1: '95', 2: '64'}, 
        {1: '17', 2: '47', 3: '82'}, 
        {1: '18', 2: '35', 3: '87', 4: '10'}, 
        {1: '20', 2: '04', 3: '82', 4: '47', 5: '65'}, 
        {1: '19', 2: '01', 3: '23', 4: '75', 5: '03', 6: '34'},

        {1: '41', 2: '41', 3: '26', 4: '56', 5: '83', 6: '40', 7: '80', 8: '70', 9: '33'},

        {1: '70', 2: '11', 3: '33', 4: '28', 5: '77', 6: '73', 7: '17', 8: '78', 9: '39', 10: '68', 11: '17', 12: '57'},

        {1: '04', 2: '62', 3: '98', 4: '27', 5: '23', 6: '09', 7: '70', 8: '98', 9: '73', 10: '93', 11: '38', 12: '53', 13: '60', 14: '04', 15: '23'}]

You need to zip them to iterate like that:

cur = [[14, k, j] for j, k in zip(rows[14], range(15))]
