Good question! If an object is used in a Boolean context, its “truthiness” is evaluated.

An empty list, an empty set, an empty dict, the value 0 are have a truthiness of False. Otherwise, they are considered True.

In person[2] == True, the object person[2] is evaluated for truthiness first, then it is compared to True. But since you already have its truthiness, you can use it directly as the Boolean value!

If you needed the opposite condition, you can use if not person[2]:

Post back if you need more help. Good luck!!!
