I'm sorry, I did not read your question carefully enough, and missed the 
"else" part. Please read Terry's correction of my advice.

Choose "New File" in the "File" menu, then write your code in the window 
that pops up, save with "Save" (pick a meaningful name that does not collide 
with any name in Python's standard library) and finally run with "Run 
Module" in the "Run" menu.
