Python：如何解决缩进错误

Question

我的缩进错误看起来实在是没法解决了。http://pastebin.com/AFdnYcRc。

#!/usr/bin/env python
import os
import glob
import shutil
import mutagen
from sys import exit

musicdir = raw_input("What directory are the music files located in? : ")
musfile = glob.glob(musicdir + '/' + "*.mp3")
musfile1 = glob.glob(musicdir + '/' + "*.flac")
musfile.extend(musfile1)
newmusicdir = raw_input("What directory should the music files be organized into? : ")


done = False

while not done:
    for m in musfile:
        if musfile:
            try:
                musta = mutagen.File(m, easy=True)
                mar = str(musta['artist'][0])
                mal = str(musta['album'][0])
                mti = str(musta['title'][0])
                mtr = str(musta['tracknumber'][0])
                os.makedirs(newmusicdir + '/' + mar + '/' + mal + '/')
            except OSError:
                pass
            finally:
                try:
                    if m.endswith('.mp3'):
                        os.rename(m,mtr + ' - ' + mar + ' - ' + mti + '.mp3')
                        m =mtr + ' - ' + mar + ' - ' + mti + '.mp3'
                        shutil.move(m,newmusicdir + '/' + mar + '/' + mal + '/')
                    elif m.endswith('.flac'):
                        os.rename(m,mtr + ' - ' + mar + ' - ' + mti + '.flac')
                        m = mtr + ' - ' + mar + ' - ' + mti + '.flac'
                        shutil.move(m,newmusicdir + '/' + mar + '/' + mal + '/')
        elif not musfile:
                print "Looks like we're done here. Please press <enter> to exit"
                raw_input()
                sys.exit(0)

Answer 1

你有没有看过pep8（链接）？它可以自动检查你的代码有没有错误。

test.py:12:80: E501 line too long (86 characters)
test.py:18:1: W191 indentation contains tabs
test.py:32:18: E231 missing whitespace after ','
test.py:33:10: E225 missing whitespace around operator
test.py:42:16: W292 no newline at end of file

Answer 2

你有一个从第30行开始的try代码块，但里面没有except部分。

Answer 3

我没有看到你第二个 try 里有 except 这个部分。通常来说，这样会导致程序出错，但我觉得这不一定会给你带来 IndendationError（缩进错误），所以你可能还有其他问题。
