【leetcode】1108. Defanging an IP Address

题目如下：

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.

解题思路：这个题目是来搞笑的吗？

代码如下：

class Solution(object):
    def defangIPaddr(self, address):
        """
        :type address: str
        :rtype: str
        """
        return address.replace('.','[.]')
