It would be easierv to access the last element directly rather than
looping:

lastCity = route[-1]

Oops. looping -> calculating.


Thank u Steven and Alan,

I am sorry to reply late. Your replies were insightful and particularly Steven's which was more specific to my problem, although i had a slight difficulty in understanding them. I will get back to you with the problem on graph with pylab. Although i am also looking into another solutions to the same problem (me a Python newbie and programming hobbyist). i will do some programming and will get back to you with my results.

Thanks again.

George.
