问题描述
我想打开一个 unicode 文件名.以下代码:
I have a unicode filename that I would like to open. The following code:
cmd = u'cmd /c "C:\Pokxe9mon.mp3"'
cmd = cmd.encode('utf-8')
subprocess.Popen(cmd)
返回
>>> 'C:Pokmon.mp3' is not recognized as an internal or external command, operable program or batch file.
即使该文件确实存在.为什么会这样?
even though the file do exist. Why is this happening?
推荐答案
看起来您使用的是 Windows 和 Python 2.X.使用 os.startfile:
It looks like you're using Windows and Python 2.X. Use os.startfile:
>>> import os
>>> os.startfile(u'Pokémon.mp3')
不直观地，让命令 shell 做同样的事情是:
Non-intuitively, getting the command shell to do the same thing is:
>>> import subprocess
>>> import locale
>>> subprocess.Popen(u'Pokémon.mp3'.encode(locale.getpreferredencoding()),shell=True)
在我的系统上，命令 shell (cmd.exe) 编码是 cp437，但对于 Windows 程序是 cp1252.Popen 想要编码为 cp1252 的 shell 命令.这似乎是一个错误，在 Python 3.X 中似乎也已修复:
On my system, the command shell (cmd.exe) encoding is cp437, but for Windows programs is cp1252. Popen wanted shell commands encoded as cp1252. This seems like a bug, and it also seems fixed in Python 3.X:
>>> import subprocess
>>> subprocess.Popen('Pokémon.mp3',shell=True)
