Defang an IP Address in Python

To defang an IP address, you can use the replace() method to replace the dots with square brackets. Here's an example of how to do this in Python:

def defang_ip_address(ip_address):
    return ip_address.replace('.', '[.]')

ip_address = '192.168.0.1'
defanged_ip_address = defang_ip_address(ip_address)
print(defanged_ip_address)  # prints '192[.]168[.]0[.]1'

The replace() method will search for all occurrences of the string '.' in the ip_address string and replace them with '[.]'. This will produce a defanged version of the IP address.

You can also use the join() function and a list comprehension to achieve the same result:

def defang_ip_address(ip_address):
    return '[.]'.join([c for c in ip_address])

ip_address = '192.168.0.1'
defanged_ip_address = defang_ip_address(ip_address)
print(defanged_ip_address)  # prints '192[.]168[.]0[.]1'

In this example, the list comprehension creates a list of characters from the ip_address string, and the join() function joins the list elements together with '[.]' as the separator.

You can also use regular expressions to defang an IP address. Here’s an example using the re module:

import re

def defang_ip_address(ip_address):
    return re.sub(r'\.', '[.]', ip_address)

ip_address = '192.168.0.1'
defanged_ip_address = defang_ip_address(ip_address)
print(defanged_ip_address)  # prints '192[.]168[.]0[.]1'

In this example, the sub() function uses a regular expression to search for all occurrences of the dot character ('.') in the ip_address string and replaces them with '[.]'.
