写词频统计函数，下面图片第四题，该怎么做呀

import random
import string

random_str_list = ["".join(random.choices(string.ascii_lowercase, k=5)) for _ in range(10000)]
word_count_dict = {}
for v in random_str_list:
    if v in word_count_dict.keys():
        word_count_dict[v] = word_count_dict[v] + 1
    else:
        word_count_dict[v] = 1

i = 0
for key in word_count_dict:
    print(key, word_count_dict[key])
    i += 1
    if i == 9:
        break
