Word Order

    Before Python 3.7, the order is not guaranteed in dictionaries:

    from collections import Counter, OrderedDict

class OrderedCounter(Counter, OrderedDict): 
    pass

words = OrderedCounter(input() for _ in range(int(input())))
print(len(words))
print(*words.values())

    Since Python 3.7, the order is guaranteed to be kept in dictionaries which makes the code even simpler:

    from collections import Counter

words = Counter(input() for _ in range(int(input())))
print(len(words))
print(*words.values())
