Exercising Python3

After making a new web site on Google sites and and fixing my home page, I finally came back to python after one week.  Today I was practicing how to calculate distance, rate, temperature using python3 in terminal, I made a new script file called "rates_times.py" and tried the examples in there. Then I had a little problem understanding the input and the string, but Mr.Elkner help me out with it and then it made more sense. Now I ready to go to the next lesson in the "wikibook" tutorial.
