PYTHON- Credit card numbers follow a standard system. For example, Visa, MasterCard, and Discover Card all
have 16 digits, and the first digit serves to indicate the card brand. All Visa cards start with a 4;
MasterCard cards always starts with a 5; and Discover cards start with a 6. Write out a program that
prompts for a credit card number and emits the name of the brand. If the card brand cannot be
determined, the program should output "Unknown Card"
