If you type your code directly into IDLE (or the commmand line Python  
interpreter) __file__ doesn't even exist; it only has any sense when the  
code is read from an actual file.
Save your code on disk, let's say you name it example.py
Then you can execute it using
> python example.py
 from the command line; from inside IDLE, go to File | Open, locate  
example.py, press F5
