The first one runs the Python found from the environment. This means you can write a script and expect it to run on systems configured differently. You might prefer in some cases to specify a particular version of Python: #!/usr/bin/env python2.5 The second one runs a specific copy of Python (and here it is even more likely that you'll want to specify a particular version). This is important if your program is being run as a service or some other background situation where the environment isn't set up. For example Subversion hooks all run with an empty environment, and cron jobs run with a default environment which may not include python (e.g. if it is in /usr/local/bin). -- http://mail.python.org/mailman/listinfo/python-list
