    Imagine not following instructions while taking a challenge. Couldn't be me.

    import re
import email.utils

N = int(input())
REX = r"[a-zA-Z][\w\.-]*@[a-zA-Z]+\.[a-zA-Z]{1,3}"
for _ in range(N):
    EMAIL = email.utils.parseaddr(input())
    if re.fullmatch(REX, EMAIL[1]):
        print(email.utils.formataddr((EMAIL[0], EMAIL[1])))

    import re pattern = re.compile(r'^[\w.-]+@[A-Za-z]+.[A-Za-z]{1,3}$') n = int(input()) for _ in range(n): name, email = input().split() email_clean = email[1:-1] if pattern.match(email_clean): print(f"{name} {email}")

    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]}")

    from email.utils import parseaddr import re

    pattern = r'^[A-Za-z][a-zA-Z0-9.,-_]*@[a-zA-Z]+.[a-zA-Z]{1,3}$' input_no = input() address = [] for i in range(int(input_no)): e_input = input() address.append(e_input)

    for i in range(int(input_no)): name,addr = parseaddr(address[i]) match = re.match(pattern,addr) if match: print(name + "<" + addr + ">") print('Valid email')
