I'm quite new to Python and programming so I just wanted to know how to restrict the user input to a certain length. For example, if the length of a credit card number is 16 digits and I wanted to restrict the length of the input to 16, how would I go about doing that?

After they enter the number, check if the length is longer than 16. If it is, loop back and ask again. – Barmar Jul 20 '21 at 07:58
