when the code finishes, the window closes, i do a time.sleep(10) to
see what has happened.
unfortunately when there is an error it just closes the window.
anyway of seeing the error messages?
Go to the windows [Start] button. Select [Run...] and in the popup

type "cmd" as the program to run. This will open a DOS shell window (a
text window.)
Then you can run your Python script from the window prompt and it

Now I can study the output for as long as I want.
Also, I could have done this:
C:\Python31\user\lotto>..\..\python lotto_2010.py >
lotto_output.txt
and directed the output to a file for editing and/or printing.
