chmod +x mycode.py
./mycode.py

Note: . (the present directory) probably isn't in your $PATH, so you 
have to use ./ to tell the shell to look in the present directory.  Do 
"echo $PATH" to see where you can put it where it's always accessible. 
You also have to include the extension.  If you want, you can rename it 
to leave off the extension, and that will work fine.  You can also make 
a symlink, like (as root):

cd /usr/local/bin
ln -s /path/to/mycode.py mycode

~/bin is also often in the $PATH, instead of putting it in /usr/local/bin.
