Thanks for the tips. It's a 2000 line program, written by someone else.
I'm not fluent in Python, yet, but making good progress in implementing
new features. The various 'attr' facilities are a bit esoteric, but
look useful. The often found, by Google "x.foobar=123", example is a
pretty narrow focus on explaining, at least, setattr.
Yes, consistency is important here, but it may take some rewriting of
the original code.

I suspect I'm in need of setattr for this in a GUI program I'm modifying.
Initally, a variable. self.stop_time is created as type datetime.time, with
the default value 06:00:00, a time stamp, during entry into the mainloop.
self.stop_time = datetime.time(10,10,10). The user reads his configuration
file with the time stamp value of 08:00:00. self.time_stop becomes type
string. He then goes to a dialog to change time stop, and it tries to access
self.time_stop, and find is needs to have the attribute strftime, as in:
set_loc_dict[ "stop_time" ] = self.stop_time.strftime("%H:%M:%S")
When reading the configuration file, how do I make sure that self.time_stop
is really has the strftime attribute?
close. what you need is hasattr(), which returns True/False. you can
also use getattr() with a default value as well. the problem you're
facing is that the object is now a str and not a datetime.time as you
mentioned. you have 2 options:
a. keep everything as a string and manipulate the value that way, or
b. convert the string to a datetime.time object and keep it like that
good luck!

Shhhh, quiet. I'm thinking about filling this space.
