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!
