Question 1: Interval Equality Let us start by implementing equality. We leave this to you. [ ] ### Defining Equality def interval_equality(self, other): """Return True iff the intervals self and other are equal, and False otherwise.""" ### YOUR CODE HERE Interval. eq_ = interval_equality [] i = = Interval (3, 5) Interval(4, 5) j i == # Tests for equality. 5 points. = i = Interval(3, 5) j Interval(4, 5) assert i != j assert Interval (5, 7) == Interval (5, 7) assert Interval (2.3, 3.4) Interval(2.3, 3.4) == Union We define union for you, to give you an example. def interval_or(self, other): """Union of self and other. Returns a list of 1 or 2 non-overlapping intervals."" if self.xl
