Intro to CS: Lecture 20 - Fitness Tracker OOP Example

Topics:  Inheritance: more examples

Reinforcing same concept as previous lectures but with a more involved example. I learned something new. You can get the class state by doing something like this: SimpleWorkout.__dict__.keys() You can do the same on an instance variable.

Most of this was review for me, again. I’ll keep mentioning that.

Object Oriented Design: More Art than Science

  • OOP is a powerful tool for modularizing your code and grouping state and functions together
  • BUT
  • It is possible to overdo it (aka over-engineering)
    • New OOP programmers often create elaborate class hierarchies
    • Not necessarily a good idea
    • Think about the users of your code
      • Will your decomposition make sense to them?
    • Because the function that is invoked is implicit in the class hierarchy, it can sometimes be difficult to reason about control flow
