Credit card numbers follow a standard system. for example, visa, mastercard, and discpver 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 american express cards start with a 2. write a program that prompts for a 16-digit credit card and emits the name of the brand. use the try/except/else structure to ensure the user enters digits only. if the card brand cannot be determined or if the correct number of digits was not entered, the program should output "unknown card."
