在python字符串中处理ascii char [英] Handling ascii char in python string

问题描述

我有一个名称为"SSE-Künden, SSE-Händler.pdf"的文件，当我在python解释器上打印此文件名时，该文件具有这两个unicode char ( ü,ä)，unicode值已转换为相应的ascii值，我猜是'SSE-K\x81nden, SSE-H\x84ndler.pdf'，但我想

i have file having name "SSE-Künden, SSE-Händler.pdf" which having those two unicode char ( ü,ä) when i am printing this file name on python interpreter the unicode values are getting converted into respective ascii value i guess 'SSE-K\x81nden, SSE-H\x84ndler.pdf' but i want to

测试目录包含名称为SSE-Künden，SSE-Händler.pdf"的pdf文件.

test dir contains the pdf file of name 'SSE-Künden, SSE-Händler.pdf'

我尝试了这个: 路径='C:\ test' 对于os.walk(path)中的a，b，c: 打印c

i tried this: path = 'C:\test' for a,b,c in os.walk(path): print c

['SSE-K\x81nden, SSE-H\x84ndler.pdf']

我该如何将ascii字符转换为各自的unival val，我想在解释器上显示原始名称("SSE-Künden, SSE-Händler.pdf")，并按原样写入某些文件.我如何实现这一点.我正在使用Python 2.6和Windows OS.

how do i convert this ascii chars to its respective unicode vals and i want to show the original name("SSE-Künden, SSE-Händler.pdf") on interpreter and also writeing into some file as it is.how do i achive this. I am using Python 2.6 and windows OS.

谢谢.

推荐答案

假设您的终端支持显示字符，请遍历文件列表并单独打印(或使用Python 3，它在列表中显示Unicode):

Assuming your terminal supports displaying the characters, iterate over the list of files and print them individually (or use Python 3, which displays Unicode in lists):

Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> for p,d,f in os.walk(u'.'):
...  for n in f:
...   print n
...
SSE-Künden, SSE-Händler.pdf

还请注意，我为路径使用了Unicode字符串(u'.').这指示os.walk返回Unicode字符串而不是字节字符串.在处理非ASCII文件名时，这是一个好主意.

Also note I used a Unicode string (u'.') for the path. This instructs os.walk to return Unicode strings as opposed to byte strings. When dealing with non-ASCII filenames this is a good idea.

在Python 3中，默认情况下，字符串为Unicode，并且向用户显示非ASCII字符，而不是将其显示为转义码:

In Python 3 strings are Unicode by default and non-ASCII characters are displayed to the user instead of displayed as escape codes:

Python 3.2.1 (default, Jul 10 2011, 21:51:15) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> for p,d,f in os.walk('.'):
...  print(f)
...
