txt = open("红楼梦.txt","r",encoding='utf-8').read()
'''
不写明路径的话，默认和保存的python文件在同一目录下 注意打开格式是utf-8，这个可以打开txt文件，选择另存为，注意界面右下角的格式
'''
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
'''
如果字典中没有这个健（名字）则创建，如果有这个健那么就给他的计数加一
[姓名:数量]，这里是数量加一
'''
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))
