如何将普通代码转换为 pythonic 面向对象的方式？

Question

import ipaddress
ip_address = list(map(str, input().split()))
def validated(ip):
   octet = ip.split(".")
   if len(octet) != 4:
       return False
   for bit in octet:
       if not isinstance(int(bit), int):
           return False
       if int(bit) < 0 or int(bit) > 255:
           return False
   return True

lst = []   
for ip in ip_address:
    if validated(ip):
        binary = bin(int(ipaddress.IPv4Address(ip)))
        octal = oct(int(ipaddress.IPv4Address(ip)))
        hexa = hex(int(ipaddress.IPv4Address(ip)))
        lst.append([binary, octal, hexa])

with open('conversion.txt' , 'w') as f:
      for ip in lst:
          f.writelines("%s\n" %ip)

d = {0:'first',1:'second',2:'third',3:'fourth',4:'fifth',5:'sixth',6:'seventh',7:'eighth',8:'ninth',9:'tenth'}    
with open('conversion.txt', 'r') as f:
     for i,line in enumerate(f):
        print(f"The {d[i]} IP address in Decimal, Binary, Octal and Hexadecimal format is {line}") 

这是我的代码，它将 IP 地址作为用户的输入进行验证，然后将十进制格式的 IP 地址转换为二进制、八进制和十六进制格式，然后将其存储到我的预定义列表中。将其存储到列表中后，我重定向了它的所有内容到一个文件中，然后我逐行从列表中获取内容并将其输出到我的控制台。 我正在尝试将其转换为面向对象的方式，但我无法有效地做到这一点，我不知道每次都出了什么问题。我是编程新手，请帮帮我。 这就是我试图这样做的。

#List to store ip address in different format
lst = []
#importing modules
import ipaddress

def validated(ip):
"""Check if entered ip is valid or not"""
    octet = ip.split(".")
    if len(octet) != 4:
        return False
    for bit in octet:
        if not isinstance(int(bit), int):
            return False
        if int(bit) < 0 or int(bit) > 255:
            return False
    return True
def ipFormatConvertor(ip):
    #Convert ip from decimal to binary
    binary = bin(int(ipaddress.IPv4Address(ip)))
    #Convert ip from decimal to octal
    octal = oct(int(ipaddress.IPv4Address(ip)))
    #Convert ip from decimal to hexadecimal
    hexa = hex(int(ipaddress.IPv4Address(ip)))
    t = (binary, octal, hexa)
    return t

def main():
#Taking ipaddress as input from user
ip_address = list(map(str, input().split()))
for ip in ip_address:
    #Checking if entered ip is valid or not.
    if validated(ip):
        output = ipFormatConvertor(ip)
        lst.append([output[0], output[1], output[2]])


 #Redirecting content of lst to file.
with open('conversion.txt' , 'w') as f:
    for ip in lst:
        f.writelines("%s\n" %ip)
d ={0:'first',1:'second',2:'third',3:'fourth',4:'fifth',5:'sixth',6:'seventh',7:'eighth',8:'ninth',9:'tenth'}
 #Taking ip address stored in file to print it to console.
with open('conversion.txt', 'r') as f:
    for i,line in enumerate(f):
        print(f"The {d[i]} IP address in Decimal, Binary,Octal and Hexadecimal format is {line}")
