Using python
Problem 9 (25 points). Given a binary number convert the number to its decimal equivalent. If the number inputted by the use contains any digits apart from 0 or 1 output and error message. Sample program output 1: Please enter the binary number: 10010 The decimal equivalent of 10010 is 18 Sample program output 2: Please enter the binary number: 111 The decimal equivalent of 111 is 7 Sample program output 3: Please enter the binary number: 2019 The decimal equivalent of 2019 is not a binary number Using python
