> но через функции и map, но не используя циклы
Ну если строго функции и map и не используя циклы - тогда вот:
def count_word(word):
if word in total_count:
total_count[word] += 1
else:
total_count[word] = 1
total_count = dict()
list(map(lambda x: count_word(''.join(filter(str.isalpha, x.lower())), str1.split())) # в str1 - ваш текст
print(total_count)
