You need some deeper understanding of what import does and what happens 
when you import again (after the library files have changed).
Try in the IDLE menu [Shell] "Restart Shell" (Ctrl+F6) each time you 
have changed something in your files - this "resets" anything previously 
imported, which stays the same way otherwise.
