I want to convert an input from Celsius to Fahrenheit but I don’t understand how to accept negative and decimal inputs while also eliminating the non digit inputs like ‘abc’.

            `temp = input('enter a temperature in C: ')

            if temp.isdigit():
                temp = int(temp)
                print(f'{temp * 1.8 + 32} F')
            else:
                print('not a temp')`
