How to convert a two dimensional list into a list of each row

Question

A=[[1,3,5,7],[2,5,8,12,16],[4,7,8,12]]

I would like the result to be

[1,3,5,7][2,5,8,12,16][4,7,8,12]

You can't put lists next to each other like that. Do you want a string of your lists? `"[1,3,5,7][2,5,8,12,16][4,7,8,12]"`? — Nick Parsons, Sep 14 '19 at 07:47
Yes as Nick said, you should be getting either string of lists, or list of lists or so. — amrs-tech, Sep 14 '19 at 08:01

you can unpack your list A like this:

A = [[1,3,5,7],[2,5,8,12,16],[4,7,8,12]]

list1, list2, list3 = A

print(list1, list2, list3)

output:

[1, 3, 5, 7] [2, 5, 8, 12, 16] [4, 7, 8, 12]

in this case, you have to be sure that A has always 3 lists inside

So what if its more than 3 list ? – Gamer19 Sep 14 '19 at 16:18
This works but how do you use it in list comprehension – Gamer19 Sep 14 '19 at 21:59
