Python实现文件（xml,txt）编码转换GB2312、GBK、UTF-8

import chardetfilename = './flash.c'
with open(filename, 'rb') as f:data = f.read()encoding_type = chardet.detect(data)print(encoding_type)

运行结果：

预先知道文件编码格式后，UTF-8编码转为GB2312，其他格式转换也是如此，示例代码：

import chardet
import codecsfilename_in = 'flash.c'
filename_out = 'flash_gb2312.c'# 输入文件的编码类型
encode_in = 'utf-8'# 输出文件的编码类型
encode_out = 'gb2312'with codecs.open(filename=filename_in, mode='r', encoding=encode_in) as fi:data = fi.read()with open(filename_out, mode='w', encoding=encode_out) as fo:fo.write(data)fo.close()with open(filename_out, 'rb') as f:data = f.read()print(chardet.detect(data))

运行结果：
