Validating IP Addresses Function

MediumPython

Problem

Write a function that checks for valid IP addresses.

For this exercise, treat an address as valid only when it is an IPv4 address in dotted-decimal notation. Return True for four numeric octets from 0 through 255, with no leading zeros except for the value 0; otherwise return False.

Use the signature def is_valid_ip(address):, where address is a string and the result is a boolean.

Constraints

1 <= len(address) <= 100
The input contains printable characters
A valid address has exactly four decimal octets separated by periods
Each octet must be in the range 0 through 255
Leading zeros are not permitted except in the octet 0

Function Signature

def is_valid_ip(address):
