How do I check if a string is a valid IP address in Python using the ipaddress module?

To check if a string is a valid IP address in Python using theipaddress module, you can follow these steps: 1. Import the necessary modules: - Import theipaddress module, which provides classes and functions for working with IP addresses and networks. - Example:

1
2

import ipaddress

2. Check the IP address: - Use atry-except block to catch anyValueError raised when the IP address is not valid. - Use theip_address() function from theipaddress module to create anIPAddress object by passing the string as an argument. - If the IP address is valid, the function call will succeed. If it is invalid, aValueError will be raised. - Example:

1
2
3
4
5
6
7

def is_valid_ip_address(address):
    try:
   ipaddress.ip_address(address)
   return True
    except ValueError:
   return False

3. Use the function: - Call theis_valid_ip_address() function and pass the string you want to validate as an IP address. - It will returnTrue if the string is a valid IP address, andFalse otherwise. - Example:

1
2
3
4
5
6

ip = "192.168.0.1"
if is_valid_ip_address(ip):
    print("Valid IP address")
else:
    print("Invalid IP address")

By following these steps, you can check if a string is a valid IP address using theipaddress module. Remember to handle any exceptions or error cases that may arise during the validation process to ensure the stability of your program.
