Make a bomb squad simulation program called bomb.py

• Define three constants at the top with different integers, NOTHING_YET, WIN, LOSE
• Create three classes: Wire, TriggerWire, and TimerWire
• Wire is the base class for the two others. It has two methods:
  1. SetColor(self, color): sets the color
  2. Cut(self): Cuts the wire, prints a message, and returns NOTHING_YET
• TriggerWire and TimerWire override Cut. TriggerWire prints a message of destruction and returns LOSE and TimerWire prints a happy message and returns WIN.
• The colors of wires should be: colors = ['red', 'green', 'blue', 'yellow', 'brown', 'pink']
• There should be one TriggerWire, one TimerWire, and the rest should be plain Wires.
• The wires should be shuffled before they are assigned colors, so that they are not the same every time. Hint: Get your program working first without shuffling, so that you know which color is which.
• There are several opportunities to use list comprehensions in this program. Use at least one of them for full credit.

Below are two example runs of the program.

1) red
