Python运行Windows Win+R(run)命令

[durden]

如下这条命令可以在Windows系统的Win+R中运行（创建outlook邮件窗口），我想在Python脚本中调用它，写法如下，但是不行，被告知outlook.exe命令不被识别，将outlook.exe文件路径写全了也不行，要怎么做呢？

import os
cmd = 'outlook.exe /c ipm.note /m [e-mail]&subject=test%20subject&body=test%20body'
os.system(cmd)

'"C:\Program Files\Microsoft Office\Office14\OU
TLOOK.EXE" /c ipm.note /m "[e-mail]&subject=test%20subject&body=tes
t%20body"'

[durden]

@clino 还是不行呢，提示the filename, directory name, or volume label syntax is incorrect，我检查了一切正常呀

import os
#cmd = r'C:\Program Files\Microsoft Office\Office12\outlook.exe /c ipm.note /m [e-mail]&subject=test%20subject&body=test%20body'
cmd = 'r"C:\Program Files\Microsoft Office\Office12\outlook.exe" /c ipm.note /m "[e-mail]&subject=test%20subject&body=test%20body"'
os.system(cmd)

[clino]

汗死... 'r"XXX"'
你这个 r 是给谁看的阿

[durden]

@clino 不加r直接报错呀“'c:\program' is not recognized as an internal or external command”

话说我浪费这么多条回复干啥呢
r'"XXX"'
