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 codecs 
import chardet

  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))
