0 3 means 3 AM.(minute 0, hour 3)

The first * means any day of the month.

The second * means any month.

The 0 at the end means Sunday.

You can choose any value from 0 to 7 where both 0 and 7 will represent Sunday.

chmod +x on the script, and add a crunch bang #!/usr/bin/python to tell it where the interpreter is
