How to create class objects for Class InfoMessafe using the show_training_info() method found in the Training base class?

Question

Python

InfoMessage class properties:
training_type — training class name;
duration — duration of the workout in hours;
distance — distance in kilometers that the user covered during the training;
speed - the average speed at which the user moved;
calories - the number of kilocalories that the user has consumed during the workout.

""" Class InfoMessage
