最近需要一个txt文件的批量转码功能，在网上找到一段批量处理java源文件的py程序如下：

#-*- coding: utf-8 -*- import codecs
import os
import shutil
import re
import chardet def convert_encoding(filename, target_encoding):
# Backup the origin file.
shutil.copyfile(filename, filename + '.bak') # convert file from the source encoding to target encoding
content = codecs.open(filename, 'r').read()
source_encoding = chardet.detect(content)['encoding']
print source_encoding, filename
content = content.decode(source_encoding) #.encode(source_encoding)
codecs.open(filename, 'w', encoding=target_encoding).write(content) def main():
for root, dirs, files in os.walk(os.getcwd()):
for f in files:
if f.lower().endswith('.txt'):
filename = os.path.join(root, f)
try:
convert_encoding(filename, 'utf-8')
except Exception, e:
print filename def process_bak_files(action='restore'):
for root, dirs, files in os.walk(os.getcwd()):
for f in files:
if f.lower().endswith('.txt.bak'):
source = os.path.join(root, f)
target = os.path.join(root, re.sub('\.txt\.bak$', '.txt', f, flags=re.IGNORECASE))
try:
if action == 'restore':
shutil.move(source, target)
elif action == 'clear':
os.remove(source)
except Exception, e:
print source if __name__ == '__main__':
# process_bak_files(action='clear')
main()
