Problem 1: Demo Tracing

class Demo:
    def __init__(self):
        self.x = []

    def add(self, v):
        self.x.append(v)

    def get_x(self):
        return self.x

A, B = Demo(), Demo()
C = B.get_x()
A.add(3)
B.add(3)
C.append(A)
print(A.get_x() == B.get_x())

Problem 2a: Smart Bulbs

• This is a coding problem. Work in pairs or trios on a single computer, and discuss your algorithm BEFORE YOU WRITE ANY CODE.
• Smart lightbulbs are used all over these days. Suppose we wanted to write some code to help manage some smart bulbs?
• Your task:
  • I’ve provided a starting class for you already in the repo for today
  • Add a method turn_on that sets the boolean to True and the brightness to 100 when called
  • Add a method turn_off that ets the boolean to False and the brightness to 0 when called

Problem 2b: Staring at the Light

• Swap who is typing!
• Implement a __repr__ method
• It should return a string like '[Kitchen: ON @ 100%]' or '[Kitchen: OFF]'
  • F-strings will be your friend to format the info!
• Bonus: Try switching the method name to __str__ and running it to compare the output

Problem 2c: Flip-Flops

• Swap who is typing!
• Write a method called toggle which toggles the state of the light
  • If the bulb is on, turn it off
  • If the bulb is off, turn it on (full brightness)
• Make sure the brightness reflects the current state of the bulb!

Problem 2d: Getting Dimmer

• Swap who is typing!
• Write a getter method (get_brightness) to return the current bulb brightness level
• Write a setter method (set_brightness) which takes a new percentage as an argument
  • If the level is greater than 100, cap it at 100
  • If the level is less than 0, cap it at 0
  • Update the boolean to reflect if the light is now on or off
