txt = open("红楼梦.txt","r",encoding=‘utf-8‘).read()

words = jieba.lcut(txt)

#利用jieba库将红楼梦的所有语句分成词汇

counts = {}

#创建的一个空的字典

for word in words:
    if len(word) == 1:      #如果长度是一，可能是语气词之类的，应该删除掉
        continue
    else:
        counts[word] = counts.get(word,0) + 1
for word in excludes:
    del(counts[word])#这一步：如果列出的干扰词汇在分完词后的所有词汇中那么删除

items = list(counts.items())
#把保存[姓名：个数]的字典转换成列表

items.sort(key=lambda x:x[1],reverse = True)

 #对上述列表进行排序，‘True‘是降序排列

for i in range(20):
    word,count = items[i]
    print("{0:<10}{1:>5}".format(word,count))
