    BTW, if you want to do it with regex, this is one way:

    import re

for _ in range(int(input())):
    r_in = r"^([a-zA-Z]+) <([a-zA-Z][\w.-]+)@([a-zA-Z]+)\.([a-z]{1,3})>$"
    found = re.match(r_in, input())
    if found:
        name, username, domain, ext = found.group(1), found.group(2), found.group(3), found.group(4)
        print(f'{name} <{username}@{domain}.{ext}>')

    import email.utils, re for i in range(int(input())): name, e=input().split() l=email.utils.parseaddr(e) if re.search(r"^a-zA-Z{1,}@([A-Za-z]{1,}).[A-Za-z]{1,3}$",l[1]): print(name, e)

    import re
import email.utils

n = int(input())
pattern = r'^[a-z](\w|-|\.)*@[a-z]+\.[a-z]{1,3}$'

for i in range(n): 
    email_string = input()
    email_string_to_check = (email.utils.parseaddr(email_string))
    if re.search(pattern, str(email_string_to_check[1])):
        print(email_string)

    Whitout email.utils -->

    import sys, re

text = sys.stdin.read().splitlines()[1:]

match_pattern = re.compile(
    r"^[a-z]+\s"
    r"<[a-z](\w|[.-])*[@][a-z]+[.][a-z]{1,3}>"
, re.I)

match_list = [re.search(match_pattern, line) for line in text]

for match in match_list:
    if match: sys.stdout.write(f'{match.group()}\n')

for i in range(n):

    if r.match(mail):
        print(email.formataddr((name,mail)))
