Is "python" an alias? In the shell, type "alias python" and
"type python".
anthgradpc7:~ cmbarton$ alias python
-bash: alias: python: not found

python is hashed (/Library/Frameworks/Python.framework/Versions/
Current/bin/python)
So what to do to make this work?
#!/usr/bin/env python ????
This works on my Mac. Does it work for others?
The use of /usr/bin/env is a hack to make it look for "python" in
$PATH. The #! syntax requires an absolute path, but there's no telling
where python will be installled (Python isn't part of POSIX, so you
can't rely up on it being installed in /usr/bin).
The actual purpose of env is to run commands with a modified
environment. The reason it's being used here (without any environment
changes) is just because it allows the program to run to be specified
as a name rather than a full path, and because /usr/bin/env will
always be available.
So is this OK? If so, we should put this in the WIKI. Is there a
better alternative, since we don't know where python is going to be
installed?
