A. (If you are less comfortable with this assignment) Write a Python program that asks for a credit card number (input as a string without hyphens or spaces, not as a number), and reports the card type (American Express, MasterCard, or Visa), and whether the card is valid. So, for the example above (4735672384163216), your program should output "4735672384163216----- ---VISA: VALID", i.e., the number as a string, 8 hyphens, and "VISA: VALID." If the entered number is anything other than a valid CC number, your program should output the number as a string, eight hyphens, and "INVALID NUMBER." In addition to your working code, you should submit a plain text file with one answer per line, for each of the following twenty CC numbers (which include valid and invalid credit card numbers of each type): 4735672384163216 5125131221485655 5451115051163662 349232661988728 4464766795523282 5549984527236360 341714386384157 5365926823264290 5213376389751262 375313685074727 5386622283419322 4225298661212573 5528322935717637 5420050412758076 5345677634360280 4581275409198311 4126427705118053 377734275639344 5141463348206102 5236758703360477 You may manually enter these numbers one at a time, or (better) read them from a file that you create. B. (If you are more comfortable with this assignment) Write a Python program that reads a text file of candidate CC numbers, one number (as a string) per line, and outputs a file with the results described above for each CC number, one per line. The CC numbers the file (of about 700 numbers) may be of any type in any order. Test your program on the file, testCCNums.txt and submit the results with your working code
