Part 2. fill Method Define a method in simpy named fill. Its purpose is to fill a simpy's values with a specific number of repeating values. The fill method will have two parameters following self: 1. The float value you are filling the values list in with. 2. The int number of values to fill in. The fill method is procedure-like in that it returns None and mutates the object the method is called on. After calling fill, the length of the Simpy object's values should be equal to the second argument given to fill. For example, consider the following usage and expected printed output, given inline, below: twos = Simpy([]) twos.fill(2.0, 3) print("Actual: ", twos, Expected: Simpy([2.0, 2.0, 2.0])") twos.fill(2.0, 5) print("Actual: ", twos, " - Expected: Simpy([2.0, 2.0, 2.0, 2.0, 2.0])") mixed = Simpy([]) mixed.fill(3.0, 3) - Expected: Simpy([3.0, 3.0, 3.0])") print("Actual: ", mixed, mixed.fill(2.0, 2) print("Actual: ", mixed, Expected: Simpy ([2.0, 2.0])") Python
