# this try/except routine is done because the information that is generated
# in a Python script is persistent between runs. Whats this means is that
# anything that is created in a python script when the script gets run a
# second, third, fourth... the objects created the first time are available to
# every run thereafter. So if you have any objects created that are static and
# do not change between runs then there is no need to make them over again.
# To test for this we simply use one of those object names that are static.
# if the object exists it will pass right on by. if it oes not it will
# generate an error that we catch in the except portion of thee code block.
# And that is where we will then create all of the static objects
