Is there another file called "calendar.py" somewhere?
MRAB, Mea culpa! There was a 'calendar.py' file I had downloaded in the past in the same directory. I assumed that Python would use the built-in one before the one in the directory. Removing that file solved the problem.
Try putting "print(calendar.__file__)" after the import in the datepicker module.
I did this prior to removing the existing calendar.py file and nothing but the two previously reported errors displayed in the terminal. It didn't point to the on-disk file. I learned a valuable lesson. Thanks very much, Rich -- https://mail.python.org/mailman/listinfo/python-list
