Python如何将文件夹中的所有txt文件的内容替换？

下面是我写的，供颂哪睁参考：

import os

path = r'D:\Desktop\e'

files = list(filter(lambda file:file[-4:]=='.txt',os.listdir(path)))

for file in files: 

 缓枣 with open(path+os.sep+file,'r+') as f:

      data = f.read()

   野岁   data.replace('wo','我')

      f.write(data)

这样编写：

fa=open("A.txt"山唤,"r"前核)

ta=fa.readlines()

fb=open("B.txt","r")

tb=fb.readlines()

tb[2:-9]=ta

fa.close()

fb.close()

fb=open("B.txt"慧唯掘,"w")

fb.writelines(tb)

fb.close()
