The most commonly used credit scoring algorithm in the U.S. is produced by the Fair Isaac Corp (FICO). FICO scores range from 300 to 850: the higher the score, the better. Every lender sets its own standards for what constitutes a good FICO score. But, in general, FICO scores fall along the following lines: FICO score Rating 760 and up Excellent 720-759 Very Good 690-719 Good 630-689 Average 300-629 Poor Assuming you have an integer variable called FICO_Score. Write Python codes using the if-then statement to assign a letter rating based on the value of FICO_Score.
