这篇文章主要介绍了Python实现批量转换文件编码的方法,涉及Python针对文件的遍历及编码转换实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了Python实现批量转换文件编码的方法。分享给大家供大家参考。具体如下：

这里将某个目录下的所有文件从一种编码转换为另一种编码,然后保存

				?

									import os

									import shutil

									def match(config,fullpath,type):

									  flag=False

									  if type == 'exclude':

									    for item in config['src']['exclude']:

									      if fullpath.startswith(config['src']['path']+os.path.sep+item):

									        flag=True

									        break

									  if type=='filter':

									    for item in config['src']['filter']:

									      if fullpath.endswith(item):

									        flag=True

									        break

									  return flag

									def conver_file(param):

									  for root, dirs, files in os.walk(param['src']['path']):

									    for filename in files:

									      readfile=root+os.path.sep+"%s" %filename

									      print(readfile)

									      if 'filter' in param['src']:

									        if not (match(param,readfile,'filter')):

									          continue

									      s=''

									      outfile=readfile.replace(param['src']['path'],param['dest']['path'])

									      try :

									        s=open(readfile,encoding=param['src']['encoding']).read()

									      except:

									        print("file %s read erro" % readfile)

									        shutil.copy(readfile,outfile)

									      if s: #False and

									        print("save")

									        with open(outfile, mode='w', encoding=param['dest']['encoding']) as a_file:

									          a_file.write(s)

									    for dirname in dirs:

									      file=root+os.path.sep+"%s" %dirname

									      if 'exclude' in param['src']:

									        if(match(param,file,'exclude')):

									          continue

									      outdir=file.replace(param['src']['path'],param['dest']['path'])

									      #print(outdir)

									      if not os.path.isdir(outdir):

									        os.mkdir(outdir)

									if __name__ == "__main__":

									  param={'src':{'path':r'D:\work\test\trunk','encoding':'gbk','exclude':['dataa'],'filter':['.php','.html','.htm']},

									    'dest':{'path':"f:\\test\\new",'encoding':'utf-8'}}

									  conver_file(param)
