Hi Arun, thank you for your assistance. The code for part 1 worked
perfectly.

I am including here a list of all of the site names for part 2. Due to
the nature of the station ids it has been difficult for me to find a
good pattern to use with regular expressions.

Thank you all in advance for your assistance.
