1108. Defanging an IP Address

🟩 Easy

Question

Given a valid (IPv4) IP address, return a defanged version of that IP address.

A defanged IP address replaces every period "." with "[.]".

Example 1:

Input: address = "1.1.1.1"
Output: "1[.]1[.]1[.]1"

Example 2:

Input: address = "255.100.50.0"
Output: "255[.]100[.]50[.]0"

Constraints:

• The given address is a valid IPv4 address.

Code

def defangIPaddr(self, address: str) -> str:
    return address.replace(".","[.]")

def defangIPaddr(self, address: str) -> str:
    defang = ""
    for i,c in enumerate(address):
        defang += '[.]' if c == '.' else c
    return defang
