Bite 109. Workout dict lookups and raising an exception

In this Bite you learn how to lookup values from a dictionary or in Python: dict.

You are presented with workout_schedule with keys: days and values: workouts. Complete get_workout_motd that receives a day string, title case it so the function can receive case insensitive days, look it up in the dict and do two things:

  • If the day (key) is not in the dictionary, raise a KeyError, we don't want this function to continue, the caller needs to catch this exception,
  • If the key is in the dictionary, return chill or go_train depending if it's a Rest day or not. The latter you will need to string-interpolate using format.
