Hello! I need helps on this question. Please concern to all the requirements and the question are asking for, and make sure it works. I got a few feedback that the code couldn't run or missing.

Thank you so much!

1. Task Write a file named credit_card.py containing a single function, check. Check accepts a single input - a positive integer. It returns True if the integer represents a valid credit card number. As with all functions that return a bool value, if it does not return True it should return False Credit card numbers have what is called a check digit. This is a simple way of detecting common mis-typings of card numbers. The algorithm is as follows 1. Form a sum of every other digit, including the right-most digit; so 5490123456789128 (5490123456789128) sums to 4+0+ 2+4+6+8+1+8-33 2. Double each remaining digit, then sum all the digits that creates it; the remaining digits (5 91357 9 2) in our example (5490123456789128) double to 10 18 2 6 10 14 18 4, which sums to 1+0+ 1+8+ 2+ 6+ 1+0 +1+41+8+4-37 3. Add the two sums above (33+37-70) 4. If the result is a multiple of 10 (i.e., its last digit is 0) then it was a valid credit card number. In addition to functional correctness, some points will be reserved for . having good variable names 2. having meaningful docstrings for all functions you write 2. Example Invocations When you run credit card.py, nothing should happen. It defines a function, it does not run it. If in another file (which you do not submit) you write the following import credit_card if credit_card.check (1) print ( ERROR: 1 is not valid')
