统计英文单词次数

方法一
from collections import Counter

import re

with open('../one_one.py',encoding="utf-8",)as f:
    f1 = f.read()
    rest = re.findall(r'[a-zA-Z].+',f1)

    res = Counter(rest)
    print(res)
    for k,l in res.items():
        print("%s:%s" % (k,l))

方法二
import re
with open('../one_one.py',encoding="utf-8", )as f:
    f1 = f.read()
    f2 = re.sub(r"[.?!,()/#:'=->]", ' ', f1)
    res = f1.split()
    print(res)
    dict1 = {}
    for k in res:
        if re.findall(r'[a-zA-Z]',k):
            ress =  res.count(k)
            dict1[k] = ress
    print(dict1)
    ll = sorted(dict1.items(),key=lambda x:x[1],reverse=True)
    print(ll)
