分享一个批量修改文件编码的python脚本

分享一个自己编写的递归查找子目录，将所有cpp文件编码修改为utf-8编码格式的小脚本

 #i!/usr/bin/env python3
 # -*- coding:utf-8 -*-
 import os
 import sys
 import codecs
 import chardet 
 
 def convert(filename,out_enc="UTF-8"):
   try:
     content=codecs.open(filename,'rb').read()
     source_encoding=chardet.detect(content)['encoding']
     print ("fileencoding:%s" % source_encoding)
 
     if source_encoding != None :
       content=content.decode(source_encoding).encode(out_enc)
       codecs.open(filename,'wb').write(content)
       content.close()
     else :
       print("can not recgonize file encoding %s" % filename)
   except IOError as err:
     print("I/O error:{0}".format(err)) 
 
 def explore(dir):
   for root,dirs,files in os.walk(dir):
     for file in files:
       if os.path.splitext(file)[1]=='.cpp':
         print ("fileName:%s" % file)
         path=os.path.join(root,file)
         convert(path)
