统计一篇英文文章内每个单词出现频率，并返回出现频率最高的前10个单词及其出现次数

from collections import Counter

import re
with open("a.txt","r",encoding="utf-8") as  f:
    txt =f.read()

c =re.split("W",txt)
Cnt =Counter(c)
print(Cnt)

ret =Cnt.most_common(10)
print(ret)

　　

改进版本.

from collections import Counter

import re
with open("models.py",encoding="utf-8") as f:
    txt = f.read()
c = re.split("W",txt)

Cnt =Counter(c)

#1. 获取到的是一个大字典里面统计了单词出现的次数.
print(Cnt)

ret = Cnt.most_common(10)

#2. 统计了前十个单词出现的次数.
print(ret)  

lt =[]

for i in ret:
    x= i[0]
    lt.append(x)
    
#3. 统计了前十个单词出现的次数放在了一个列表里面.
print(lt)
