我试图编写一个Python脚本,通过目录树搜索并列出所有.flac文件,并从resp派生出Arist,Album和Title。 dir / subdir / filename并将其写入文件。代码工作正常,直到它达到unicode字符。这是代码:
import os, glob, re
def scandirs(path):
for currentFile in glob.glob(os.path.join(path, '*')):
if os.path.isdir(currentFile):
scandirs(currentFile)
if os.path.splitext(currentFile)[1] == ".flac":
rpath = os.path.relpath(currentFile)
print "**DEBUG** rpath =", rpath
title = os.path.basename(currentFile)
title = re.findall(u'\d\d\s(.*).flac', title, re.U)
title = title[0].decode("utf8")
print "**DEBUG** title =", title
fpath = os.path.split(os.path.dirname(currentFile))
artist = fpath[0][2:]
print "**DEBUG** artist =", artist
album = fpath[1]
print "**DEBUG** album =", album
out = "%s | %s | %s | %s\n" % (rpath, artist, album, title)
flist = open('filelist.tmp', 'a')
flist.write(out)
flist.close()
scandirs('./')
代码输出:
**DEBUG** rpath = Thriftworks/Fader/Thriftworks - Fader - 01 180°.flac
**DEBUG** title = 180°
**DEBUG** artist = Thriftworks
**DEBUG** album = Fader
Traceback (most recent call last):
File "decflac.py", line 25, in <module>
scandirs('./')
File "decflac.py", line 7, in scandirs
scandirs(currentFile)
File "decflac.py", line 7, in scandirs
scandirs(currentFile)
File "decflac.py", line 20, in scandirs
out = "%s | %s | %s | %s\n" % (rpath, artist, album, title)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 46: ordinal not in range(128)
但是在Python控制台中尝试时,它运行正常:
>>> import re
>>> title = "Thriftworks - Fader - 01 180°.flac"
>>> title2 = "dummy"
>>> title = re.findall(u'\d\d\s(.*).flac', title, re.U)
>>> title = title[0].decode("utf8")
>>> out = "%s | %s\n" % (title2, title)
>>> print out
dummy | 180°
所以,我的问题: 1)为什么相同的代码在控制台中工作,但在脚本中却没有? 2)如何修复脚本?

Python控制台与您的终端配合使用,并根据其语言环境解释unicode编码。
用新str.format
替换该行:
out = u"{} | {} | {} | {}\n".format(rpath, artist, album, title)
写入文件时编码为utf8:
with open('filelist.tmp', 'a') as f:
f.write(out.encode('utf8'))
或import codecs
并直接执行:
with codecs.open('filelist.tmp', 'a', encoding='utf8') as f:
f.write(out)
或者,因为utf8是默认值:
with open('filelist.tmp', 'a') as f:
f.write(out)

在控制台中,终端设置定义编码。如今,这主要是unices上的Unicode,例如Windows上的Linux / BSD / MacOS和Windows-1252。在解释器中,它默认为python文件的编码,通常是ascii(除非你的代码以UTF Byte-Order-Mark开头)。
我不完全确定,但可能在字符串“%s |%s |%s |%s \ n”前加上u
前缀,以使其成为unicode字符串可以提供帮助。< / p>

通过切换到Python3解决,Python3按预期处理unicode案例 替代:
title = title[0].decode("utf8")
for:
title = title[0]
甚至不需要将“out”的值加上“u”前缀或者在写入时指定编码 我喜欢Python3。

将glob
与包含Unicode字符的文件名一起使用时,请为该模式使用Unicode字符串。这使得glob
返回Unicode字符串而不是字节字符串。输出时,打印Unicode字符串会自动将其编码为控制台的编码。如果您的歌曲具有控制台编码不支持的字符,您仍会遇到问题。在这种情况下,将数据写入UTF-8编码的文件,并在支持UTF-8的编辑器中查看。
>>> import glob
>>> for f in glob.glob('*'): print f
...
ThriftworksFaderThriftworks - Fader - 01 180░.flac
>>> for f in glob.glob(u'*'): print f
...
ThriftworksFaderThriftworks - Fader - 01 180°.flac
这也适用于os.walk
,并且是一种更简单的递归搜索方式:
#!python2
import os, fnmatch
def scandirs(path):
for path,dirs,files in os.walk(path):
for f in files:
if fnmatch.fnmatch(f,u'*.flac'):
album,artist,tracktitle = f.split(u' - ')
print 'Album: ',album
print 'Artist:',artist
title,track = tracktitle.split(u' ',1)
track = track[:-5]
print 'Track: ',track
print 'Title: ',title
scandirs(u'.')
输出:
Album: ThriftworksFaderThriftworks
Artist: Fader
Track: 180°
Title: 01
