Does this help? from collections import Counter n = int(input()) words = [] for i in range(n): words.append(input()) counter = Counter(words) print(len(counter)) print(*counter.values()) Also, no need to list() a set, you can just do len(set(...)) The reason your solution times out is because you're doing l.count(i), for each i in l; that means it's gonna go through n elements of l, then for each again traversing through l to get their count. That's n² operations. You're better off going through the list once holding the result in a dictionary. counter = dict.fromkeys(l, 0) for key in l: counter[key] += 1
