HackerRank Validating and Parsing Email Addresses solution in Python

HackerRank Validating and Parsing Email Addresses solution in Python – In this Validating and Parsing Email Addresses problem, you are given N pairs of names and email addresses as input, print each name and email address pair having a valid email address on a new line.

A valid email address meets the following criteria:

• It’s composed of a username, domain name, and extension assembled in this format: username@domain.extension
• The username starts with an English alphabetical character, and any subsequent characters consist of one or more of the following: alphanumeric characters, -,., and _.
• The domain and extension contain only English alphabetical characters.
• The extension is 1, 2, or 3 characters in length.

Hint: Try using Email.utils() to complete this challenge. For example, this code:

import email.utils
print email.utils.parseaddr('DOSHI <DOSHI@hackerrank.com>')
print email.utils.formataddr(('DOSHI', 'DOSHI@hackerrank.com'))

produces this output:

('DOSHI', 'DOSHI@hackerrank.com')
DOSHI <DOSHI@hackerrank.com>

import re
N = input()
for i in xrange(N): 
    s = raw_input()
    a = re.search(r'<[a-zA-Z][w.-]*@[a-zA-Z]*.[a-zA-Z]{1,3}>', s)
    if bool(a):
        print(s)
