sys.executable is "/usr/bin/python" or similar only when you use the
"python" executable. On the Mac, there is also a script called
"pythonw" which is needed for applications that access the window
manager (exception made for X11). This script actually calls the
executable of a Mac-style application bundle, because otherwise Mac
OS X refuses to grant it access to the window manager and its
events. The bottom line is, that when using "pythonw",
sys.executable will always be something like ".../Library/Frameworks/
Python.framework/...". If one installs Python through MacPorts, if I
recall correctly, it puts the framework in /Library/Frameworks (I
customized my installation, so I can't tell for sure). In this case
the sys.executable and sys.version_info would be pretty much what
Jouni proposed in his snippet, so I'm afraid it won't be that easy.
Am I wrong?
With kind regards,
