There is a rather standard way to achieve that in UN*X. Make the file
executable and use shebang to specify python interpreter:

$ cat demo.py
#!/usr/bin/python
import time
print "Start of program"
time.sleep(120) # Give us time to check the process
print "End of program"
$ chmod u+x demo.py
$ ./demo.py &
[1] 6767
$ Start of program

$ ps
  PID TTY          TIME CMD
 6762 pts/2    00:00:00 bash
 6767 pts/2    00:00:00 demo.py
 6768 pts/2    00:00:00 ps
$ End of program

[1]+  Done                    ./demo.py
$ 

It's not portable to other operating systems, but neither is argv
mugging.
