如何在Python中将文件转换为utf-8？

问题描述

我需要在Python中将一堆文件转换为utf-8，并且我有麻烦的转换文件部分。

I need to convert a bunch of files to utf-8 in Python, and I have trouble with the "converting the file" part.

我想做相当于：

iconv -t utf-8 $file > converted/$file # this is shell code

谢谢！

推荐答案

您可以使用，如下所示：

You can use the codecs module, like this:

import codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sourceFileName, "r", "your-source-encoding") as sourceFile:
    with codecs.open(targetFileName, "w", "utf-8") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

编辑：添加 BLOCKSIZE 参数控制文件块大小。

EDIT: added BLOCKSIZE parameter to control file chunk size.
