    I managed to use both regex and email.util

    import email.utils
import re

n = int(input())
rx = re.compile(r"^[a-zA-Z][\w\.\-_]*@[a-zA-Z]+\.[a-zA-Z]{1,3}$")
emails = [email.utils.parseaddr(input()) for _ in range(n)]
emails = filter(lambda x: rx.match(x[1]), emails)
print(*list(map(email.utils.formataddr, emails)), sep='\n')

    import email.utils import re noOfInp = int(input()) pattern = r'^[a-zA-Z]+[\w-.]+@[a-zA-Z]+.{1}[a-zA-Z]{1,3}$'

    def isValidEmail(username, mail): m = re.match(pattern, mail) if m: tupl = (username, mail) print(email.utils.formataddr(tupl))

    for i in range(noOfInp): inp = input() username = email.utils.parseaddr(inp)[0] mail = email.utils.parseaddr(inp)[1] isValidEmail(username, mail)

    import email.utils name="" user="" domain="" ext="" a=[] out="" new_str=""

    n=int(input())

    def validity(n,u,d,e):

    if u[0].isalpha() and "@" not in u:

    out=n+"<"+u+"@"
    if d.isalpha():
        out+=d
        if len(e)<=4 and len(e)>0:
            if e.isalpha():

                out+="."+e+">"        
                print(out)

    for i in range(n): a.append(input())

    for email in a: if "<" in email: name,mail=email.split("<",1) if "@" in mail: user, domain_with_ext = mail.split("@", 1)

            if "." in domain_with_ext:
            domain, exten = domain_with_ext.split(".", 1)

            if ">" in exten:
                ext,new_str=exten.split(">",1)
                validity(name,user,domain,ext)
