Stefan;
Thanks for your valuable suggestion. I have employed your suggestion
with the code below.
I also converted this to object oriented design. With this type of
construction, the
program will easily handle the dictionary specified by the self.proj
variable. This
variable is a dictionary with some of the value variables also being
dictionaries.
I did not generalize the function call but have more of horizontal
code for this
area of the implementation. If this program were packaged with a GUI,
it would
make the beginning of a project management software platform.
