python使用jieba实现简单的词频统计

import jieba
def getText():
    txt=open("hamlet.txt","r").read()
    txt=txt.lower()
    for ch in '|"#$%&()*+,-./:;<>+?@[\]^_{|}~':
        txt=txt.replace(ch," ")
    return txt
harmTxt=getText()
words=harmTxt.split()
counts={}
for word in words:
    counts[word]=counts.get(word,0)+1

items=list(counts.items())

#按照第二个元素有大到小排序
items.sort(key=lambda  x:x[1],reverse=True)

for i in range(10):
    word, count=items[i]
    print(word,end=":")
    print(count)

运行结果
