#!/usr/bin/env python
You may also need to set the executable bit on the file, which may be set using chmod +x on the command line. | 2 | 7 | 0 | I am not sure if I searched for the wrong terms, but I could not find much on this subject. I am on osx and I'd like to compile a commandline python script into a small commandline app, that I can put into usr/local/bin so I can call it from anywhere. Is there a straighforward way to do that?

Put #!/usr/bin/env python in the first line of your .py script.
Add execution permissions to the file (using chmod).
Execute the script from command line, eg. by providing ./my_script.py when in the same directory.

And you could set a unique constraint on the asset_fk so thatt it can only exist in one location at a time | 2 | 0 | 0 | I'm working through the design of a Django inventory tracking application, and have hit a snag in the model layout.
