Python os.walk使其支持Unicode / UTF

本文介绍了Python os.walk使其支持Unicode / UTF-8？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经研究了这个问题，似乎Python 2.7默认使用是ASCII，我不能切换到python 3（默认Unicode），因为库

I have researched about this issue, It seems Python 2.7 default use is ASCII, I cant switch to python 3 (default Unicode) because of libraries

＃ - * - 编码：utf-8 - * - 打印u'порядке'

似乎打印正常它将是？没有 u 但是： 打印列表（os.walk（ur'c：\somefoler'））返回 \\\и\\\т ... 为什么不可读第一印？另外我使用os.walk与变量我不能使用它与 ur 我只是想了解如何使我的以下代码工作与任何文件夹/文件语言我使用os.walk +保存到文件两者似乎总是不起作用 ???? 其中西里尔文

seems to print fine it will be ?????? without u but: print list(os.walk(ur'c:\somefoler')) returns \u0438\u0442... why not readable as first print? Also I use os.walk with variables I can't use it with ur I'm just trying to understand how could I make my following code work with any folders/files language I use os.walk + save to file both seems not to work always ???? where Cyrillic

def findit(self,root, exclude_files=[], exclude_dirs=[]): exclude_files = (fnmatch.translate(i) for i in exclude_files) exclude_files = '('+')|('.join(exclude_files)+')' exclude_files = repile(exclude_files) exclude_dirs = (os.path.normpath(i) for i in exclude_dirs) exclude_dirs = (os.path.normcase(i) for i in exclude_dirs) exclude_dirs = set(exclude_dirs) for root, dirs, files in os.walk(root): if os.path.normpath(os.path.normcase(root)) in exclude_dirs: # exclude this dir and subdirectories dirs[:] = [] continue for f in files: if not exclude_files.match(os.path.normcase(f)): yield os.path.join(root, f)

filelist = list（findit（'c：\\'，exclude_files = ['* .dll'，'* .dat'，'* .log '，'* .exe']，exclude_dirs = ['c：/ windows'，'c：/ program files'，'c：/ else']））

当它是一个变量，似乎我必须使用 .decode（'utf-8'）？为什么没有unicode如 u'var'如果它存在，为什么有很多次异常，不可能转换遇到它，并看到很多答案与这样的错误我很难理解它是不是有办法让它工作？

When it's a variable it seems I have to use .decode('utf-8')? Why not unicode such as u'var' if it exists and why there are many times exceptions it's not possible to convert had encountered it and saw a lot of answers with such errors I'm having hard time understanding it isn't there a way to make it just work?

推荐答案

尝试

root = ur'c:\somefoler' for current,dirs,files in os.walk(root): for file in files: print file, repr(file)

你应该看到正确的事情（在列表中使用的repr旁边）...问题是当您打印列表时，会打印其项目

you should see the proper thing(along side the repr that is used in the list) ... the problem is that when you print a list it prints a repr of its items
