Hi! I hope you can help me. I'm writting a simple piece of code. I need to keep asking for a number until it has all this specifications:
- It is a number - It's lenght is 3 - The hundred's digit differs from the one's digit by at least two My problem is that I enter a valid number like: 123, 321, 159, 346... and it keeps asking for a valid number. Here's mi code: res = input('Give me a number --> ') hundreds = int(res[0]) ones = int(res[2]) # checks if the user enters a valid number while not res.isdigit() or not len(res) == 3 or abs(hundreds - ones) <= 2: res = input('Enter a valid number --> ') Thanks for help! -- https://mail.python.org/mailman/listinfo/python-list
