Peter's rich uncle has promised him a payment of $4,000 if he completes college in four years. Richard has just finished a very difficult sophomore (second) year, including taking several finance courses. Richard would very much like to take a long vacation. The appropriate discount rate is 10% compounded semi-annually. What is value that Peter would be giving up today if he took his vacation? Please answer with Python code if possible. If not, I can convert the answer to code myself.
