Yes, it is working now. Thanks for the timely response.

In looking at the tutorial, the only "strings" used with boolean operators ("<" | ">" | "==" | ">=" | "<=" | "!=") were strings of the numeric variety. I saw no examples using words. I know the datetime module has a function for enumerating the days of the week, but it starts with Monday and ends with Sunday. I needed to start with Sunday and end with Saturday. The first thing I found for checking letter-filled strings was the "is" operator.

Perhaps a brief example of word comparisons in the tutorial would be useful. I know it would have helped me.

I can't say I have a clear understanding of the difference between the "is" and "==" operators, but I can accept that there apparently is some difference and there are situations where that difference matters. Again, thanks for the quick response.
