Python批量转换文件编码格式

自己写的方法，适用于linux，

#!/usr/bin/python
#coding=utf-8
import sys
import os, os.path
import dircache
import commands
def add(x,y):
 return x*y

def trans(dirname):
 lis = dircache.opendir(dirname)
 for a in lis:
af=dirname+os.sep+a
## print af
 if os.path.isdir(af):
## print af
trans(af)
else:
 ## print af+\"encoding=\"+fi.name
 ft = commands.getoutput(\'file -i \'+af)
## print ft
 if a.find(\'.htm\')==-1 and a.find(\'.xml\')==-1 and ft.find(\'text/\')!=-1 and ft.find(\'iso-8859\')!=-1:
 print \'gbk\'+ft+\">\"+af
 commands.getoutput(\'iconv -ficonv -f gbk -t utf-8 -c -o\'+\"\"+af+\"\"+af)

trans(os.getcwd())

py2.6以下版本可用代码

import os,sys 
 
def convert( filename, in_enc = \"GBK\", out_enc=\"UTF8\" ): 
  try: 
    print \"convert \" + filename, 
    content = open(filename).read() 
    new_content = content.decode(in_enc).encode(out_enc) 
    open(filename, \'w\').write(new_content) 
    print \" done\" 
  except: 
    print \" error\" 
 
def explore(dir): 
  for root, dirs, files in os.walk(dir): 
    for file in files: 
      path = os.path.join(root, file) 
      convert(path) 
 
def main(): 
  for path in sys.argv[1:]: 
    if os.path.isfile(path): 
      convert(path) 
    elif os.path.isdir(path): 
      explore(path) 
 
if __name__ == \"__main__\": 
  main() 

支持py3.1的版本

import os
import sys
import codecs
#该程序用于将目录下的文件从指定格式转换到指定格式，默认的是GBK转到utf-8 
def convert(file,in_enc=\"GBK\",out_enc=\"UTF-8\"):
try:
print (\"convert \" +file)
f=codecs.open(file,\'r\',in_enc)
new_content=f.read()
codecs.open(file,\'w\',out_enc).write(new_content)
#print (f.read())
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:
path=os.path.join(root,file)
convert(path)

def main():
for path in sys.argv[1:]:
if(os.path.isfile(path)):
convert(path)
elif os.path.isdir(path):
explore(path)

if __name__==\"__main__\":
main()
