PYTHON (pycharm) - credit card check application
Credit card companies typically assign a special digit, called a check digit, to the end of each customers credit card number. The check digit allows companies to verify that the credit card number was entered accurately. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:
Starting from the right most digit, form the sum of every other digit. For example, if the credit card number is 4358 9795, then you form the sum 5+7+8+3 = 23.
Double each of the digits that were not included in the preceding step. Add all digits of the resulting numbers. For example, with the number given above, doubling the digits, starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these values yields 1+8+1+8+1+0+8 = 27.
Add the sums of the two preceding steps. If the last digit of the result is 0, the number is valid. In our case, 23 + 27 = 50, so the number is valid.
Create the Credit Card Check Application. The application should implement the above algorithm. The user should supply an 8-digit number, and you should print out whether the number is valid or not. The program output should be formatted as shown in the Sample Run.
Note: You must use at least one for loop in your code.
