Running Python programmes

[David]

I am an absolute beginner and am working through the book Python Programming for the Absolute Beginner by Michael Dawson.  Everything is fine except if I run a scripted programme, or one I have downloaded, and then run another one, the second one will not run, I just get the >>> in the interactive window.  I have to exit Python and start again, when the second programme then runs fine.

Any suggestions much appreciated.
