/How/ do you "run" the program for Guido's sake?!

The solution to get answers is to give details.

But to play the clairvoyant:

/If/ you tried to run the program from a command prompt or from by
klicking on the file there should be no problems.

/If/ you tried to run the program by importing it from the Python
shell, then this is normal. A hyphen is not allowed in module names at
it is the same character as in subtractation.
