In this Bite you learn how to lookup values from a dictionary or in Python:
You are presented with
WORKOUT_SCHEDULE dict(constant) with keys = days and values = workouts (or rest up). Complete
get_workout_motdthat 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, return
INVALID_DAY, we don't want this function to continue.
- If the key is in the dictionary, return
TRAINdepending if it's a
RESTday or not. The latter you will need to string-interpolate using
Also check out the docstring and tests. Have fun and keep calm and code in Python!
Update 25th of Nov 2019: previously this Bite required re-raising the
KeyError, but as that's already the default behavior of a missing key in a dict, we changed the requirements to return a value instead.
