Python作业：jieba库

运用jieba库统计词频，并对词频进行排序

import jieba
txt = open("文章.txt","r",encoding='gbk',errors='replace').read()
words  = jieba.lcut(txt)
counts = {}
for word in words:
    if len(word) == 1:
        continue
    else:
        counts[word] = counts.get(word,0) + 1
        
items = list(counts.items())
items.sort(key=lambda x:x[1], reverse=True) 
for i in range(15):
    word, count = items[i]
    print ("{0:<10}{1:>5}".format(word, count))
