Validating and Parsing Email Addresses

    I didn't use emails.utils for my solution. Find my code below.

    Just to precise, I started by splitting username / domain and extension into differents variables, then, I have created 3 differents regex pattern, to check if each one works.

    When it was done, I've removed the split for username / domain and extension, then merge the 3 differents regex pattern into a big one.

    And finally, it pass all the tests : 

    # Enter your code here. Read input from STDIN. Print output to STDOUT
import re
import email.utils


n = int(input())
output = list()
for _ in range(n):
    current_line = input().split()
    if "@" in current_line[1]:
        current_name = current_line[0]
    
        current_mail = current_line[1]
        current_mail = current_mail[1:-1]
    
        pattern = r"^([A-Za-z][A-Za-z0-9\_\-\.]+)@([A-Za-z]+)([.])([A-Za-z]{1,3})$"
        
        # Debug check
        #print(bool(re.match(pattern, current_mail)))
    
        if bool(re.match(pattern, current_mail)):
            output.append(current_line)
        else:
            continue
    else:
        continue

for element in output:
    print(f"{element[0]} {element[1]}")
