使用python在目录中列出中文文件名 [英] Listing chinese filenames in directory with python

问题描述

我试图列出目录中所有文件的名称和大小，但是当中文文件出现错误时，我在Windows 7上使用Python 2.7

I am trying to list the names and sizes of all files in a directory but get an error when there are files in chinese, i am using Python 2.7 on windows 7

这是我的代码

import os

path = '\'
listing = os.listdir(path)
for infile in listing:
    if infile.endswith(".csv"):
        print infile + ";"+ str(os.path.getsize(path + infile))

这是我得到的错误

Traceback (most recent call last):
  File "file_size.py", line 8, in <module>
    print infile + ";"+ str(os.path.getsize(path + infile))
  File "C:\Python27\lib\genericpath.py", line 49, in getsize
    return os.stat(filename).st_size
WindowsError: [Error 123] The filename, directory name, or volume label syntax is incorrect: '\DB?1333366331.436754.048342.csv'

C:\>python file_size.py
  File "file_size.py", line 7
    if infile.endswith(".csv"):
                              ^
IndentationError: unindent does not match any outer indentation level

引起错误的文件名是DB表1333366331.436754.048342.csv

The name of the file that caused the error is DB表1333366331.436754.048342.csv

我该如何避免这个问题？

How can i avoid this problem?

预先感谢 p>

thanks in advance

推荐答案

我会尝试使您的根路径成为unicode。我的猜测是listdir使用与初始字符串相同的编码，并且在读取非ASCII字符时出错。

I would try making your root path unicode. My guess is that listdir is using the same encoding as the initial string and is erroring when reading the non-ascii character.

即

path = u'\'

来源：
http://docs.python.org/library/os.html#os.listdir

在版本2.3中进行了更改：在Windows NT / 2k / XP和Unix上，如果path是Unicode对象，则结果将是Unicode对象的列表。无法解码的文件名仍将作为字符串对象返回。

"Changed in version 2.3: On Windows NT/2k/XP and Unix, if path is a Unicode object, the result will be a list of Unicode objects. Undecodable filenames will still be returned as string objects."
