Answer 2

i have a version very similar to visph's, but using a dictionary instead of a list.

input:
['1.b', '1.b', '2.b', '2.c', '3.b', '1.c', '12.a']

output:
('1', 'b,b,c')
('2', 'b,c')
('3', 'b')
('12', 'a')

Answer 3

If there was another item in pylist at end like "1.c", so then output for first array would be ("1", "b, b, c") ?

Answer 4

Siva Pitchai you must:

1) create a new list to store result
2) iterate over pylist and for each item:
a) split string at dot
b) search if new list contains an item with first value equals to first value of splited string:
• if so, update second value to append second value of splited string
• if not, append a new item to new string with splited string
3) finally sort new list by first value in items
4) output the new list content formated as you want
