After programming for a year I re-wrote IP to Binary. making the same output with 1/3 of the lines.

IP to Binary 2

class converter:
    def __init__(self):
        self.ip = input('Enter an IP Address: ')
        self.binary = [128,64,32,16,8,4,2,1]
        self.empty_list = []

    def convert(self, number):
        empty_string = ''
        number = int(number)
        for num in self.binary:
            if number >= num:
                empty_string += '1'
                number -= num
            else:
                empty_string += '0'
        return empty_string

    def seperate(self, ip):
        ip = ip.split('.')
        return ip

    def main(self):
        for num in C.seperate(self.ip):
            new = C.convert(num)
            self.empty_list.append(new)
        print('Your IP: ' + '.'.join(self.empty_list))

C = converter()
C.main()
