Validating and Parsing Email Addresses in Python - HackerRank Solution
Validating and Parsing Email Addresses in Python - HackerRank Solution
Problem :
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>
Input Format :
The first line contains a single integer, n, denoting the number of email address.Each line i of the n subsequent lines contains a name and an email address as two space-separated values following this format:
name <user@email.com>
Constraints :
- 0 < N < 100
Output Format :
Print the space-separated name and email address pairs containing valid email addresses only. Each pair must be printed on a new line in the following format:name <user@email.com>
You must print each valid email address in the same order as it was received as input.
Sample Input :
2 DEXTER <dexter@hotmail.com> VIRUS <virus!@variable.:p>
Sample Output :
DEXTER <dexter@hotmail.com>
Explanation :
dexter@hotmail.com is a valid email address, so we print the name and email address pair received as input on a new line.virus!@variable.:p is not a valid email address because the username contains an exclamation point (!) and the extension contains a colon (:). As this email is not valid, we print nothing.
