Validating and Parsing Email Addresses Problem

This Python program is designed to validate and parse email addresses. It takes a number of email addresses as input and checks each one to see if it matches a specific pattern. If the email address is valid, it is printed out.

Here is the Validating and Parsing Email Addresses Problem HackerRank solution using CodeRankGPT:

The solution works by using the 'email.utils' and 're' modules in Python. The 'email.utils' module is used to parse the email address, and the 're' module is used to match the parsed email against a regular expression pattern. The pattern checks if the email starts with an alphabet character, followed by any combination of alphabets, numbers, periods, underscores, and hyphens. This is followed by an '@' symbol, then another set of alphabets, a period, and finally 1 to 3 alphabet characters. If the email matches this pattern, it is considered valid and is printed out.


import email.utils
import re

n = int(input())
for _ in range(n):
    s = input()
    parsed_email = email.utils.parseaddr(s)[1].strip()
    match_result = bool(
        re.match(
            r"(^[A-Za-z][A-Za-z0-9\._-]+)@([A-Za-z]+)\.([A-Za-z]{1,3})$", parsed_email
        )
    )
    if match_result:
        print(s)
