[Saravanakumar Karunanithi]

my_list = [['NM100', 1, 2], ['NM100', 3, 4], ['NM200', 5, 6]]
temp_dict = {}
for each in my_list:
    if each[0] in temp_dict.keys():
        temp_dict[each[0]].extend(each[1:])
    else:
        temp_dict[each[0]] = each[1:]
print [[k] + v for k,v in temp_dict.iteritems()]
