I have a sorted list that will have a list of lists with repeated index0. Based on the index0 from each list, i will have to add the index3 and then join the strings in index4. Index#3 will be always numbers - this should be added if there is any repeated index#0 Index#4 could be anything - this should be merged and there shouldn't be any repeated strings/numbers after merge.
As an example, the result of the above list should be something like:
final_lst = [
['04-0200', 'str1', '7', 'n1,n2,n3,n4,n5,n6'],
['11-0200', 'str3', '1', 'u1'],
['19-0000', '', '2', ''],
['19-0201', 'str4', '5', 'p1,p2,p3'],
['22-0001', 'str5', '191', 'a1,a2,a3,a4,b1,b2,b3,b4,b5,c1,c2'],
['9-02011', 'str8', '3', '', 'x,y,z']
]
