George uses the services of a brokerage firm to buy and sell stocks. Each time he buys or sells a block of stocks, he must pay the brokerage firm a commission of 1.5% per share. Design a program that allows George to enter the number of shares in the block, the price per share when he bought the block and the price per share when he sold the block. The program should display the amount of money he paid to buy the stock and the amount of the commission. The amount of money he made when he sold the stock and the amount of the commission, the amount of profit (or loss) he made after paying for the purchase cost and both commissions. Do so in Python.
