i tried to run it in a interactive interpreter then it works like a comment but when i run it as a program all it does is to 'restart'? what does this mean? thanks

#!/whatever just tells the shell you're using to execute that interpreter for that file. it's the shell that interprets the #!/whatever, not python.

Specifically that refers to the linux interpreter, I'm not so sure that would be right under windows for instance.

usually what you do under linux is specify that in the first line and then assign the script executable permissions, then it can be run without specifying the interpreter in the command line e.g:

(Toggle Plain Text)

:~$ python scriptname.py
