Day 74 [November 20, 2025]

I need to buckle down, as I'm still lagging on day day 3 & 4 goals, "Day 3-4: Control structures (if-else, loops)", as well as day 5 (and 6) goals, "Day 5-6: Functions and modules", and Day 7 target (exercises) (Meta AI, personal communication, August 8, 2025). If I haven't covered this, I can't make progress on day 8 - 73 goals.

Goals:

Sets:

.difference method shows us the elements of one set (e.g. setBIg) that are not found in the other(setCar): setBig.difference(setCar) [note the arrangement of the set, because reversing the arrangement of the set, is different from the other).

Summary:
The difference method shows us the elements of one set that are not found in the other.
