os.path.abspath超级奇怪的错误 [英] A super strange bug of os.path.abspath
问题描述
在我的Python 2.6(64bit,win7,ActivePython),
当我打电话时:
os.path.abspath('D:/ PROJECTS / SuiShouBei / www / ssb它返回:
<$ c $ / code c>'\\\\\\\\''
到目前为止,我对其他路径没有任何问题。
任何人都有同样的问题?
有人可以告诉我为什么?
我可以在Python 2.6,2.7,3.1和3.2中重现这个问题。
这个行为的原因是 CON
是一个非法文件名(尝试 os.path.abspath('D:/PROJECTS/SuiShouBei/www/ssb/static/voices/en/mp3/cont.mp3')$ c $请注意,你的文件名不包含
<$ p
< (小于)
> (大于)
:(冒号)
(双引号)
/(正斜杠)
\(反斜杠)
|(竖线或竖线)
?(问号)
*(星号)
以下保留的设备名称为文件名(带或不带扩展名):
CON,PRN,AUX,NUL, COM1,COM2,COM3,COM4,COM5,COM6,COM7,COM8,COM9,
LPT1,LPT2,LPT3,LPT4,LPT5,LPT6,LPT7,LPT8和LPT9
正如slowdog所注意到的,它在与上面相同的MSDN文档 \\\\\\\
是正确的直接访问这样一个设备名称的方法。
On My Python 2.6 ( 64bit, win7, ActivePython ),
when i call:
os.path.abspath('D:/PROJECTS/SuiShouBei/www/ssb/static/voices/en/mp3/con.mp3')
It returns:
'\\\\.\\con'
I have no problem with other paths so far.
Anyone has the same issue?
Can someone please tell me why?
I can reproduce this in Python 2.6, 2.7, 3.1 and 3.2.
The reason for this behavior is the fact that CON
is an illegal filename in Windows (try os.path.abspath('D:/PROJECTS/SuiShouBei/www/ssb/static/voices/en/mp3/cont.mp3')
and see that everything works fine).
So take care that your filenames don't contain
< (less than)
> (greater than)
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)
Also do not use the following reserved device names for the name of a file (with or without extension):
CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9,
LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9.
As noticed by slowdog, it is mentioned in the same MSDN document as above that \\.\CON
is the correct way to access such a device name directly.
