python按照单词出现频率排序输出

一行四个词

import re

fp = open("wanxing.txt", "r",encoding = 'utf-8')
article = fp.read()
new_article = re.sub(r'[^A-Za-z]', ' ', article)
words = new_article.split()
word_counts = {}
for word in words:
    if word.lower() in word_counts:
        word_counts[word.lower()] = word_counts[word.lower()] + 1
    else:
        word_counts[word.lower()] = 1

order = sorted(word_counts.items(), key=lambda v: v[1],reverse=True)
n = 0
for key in order:
    if key[1] >= 3:
        n = n + 1
        print("{}:{}tttt".format(key[0],key[1]),end="")
        if n % 4 == 0:
            print("n")
