    I cannot seem to pass testcase 5, any help?

    def fun(s): if '@' not in s: return False

    try:
    username_website, extension = s.rsplit('.',1)
    username,website = username_website.split('@')
except ValueError:
    return False

for char in username:
    if not(char.isalnum() or char in ['-','_']):
        return False

if not(website.isalnum()):
    return False

if not (extension.isalpha()) or not(1<=len(extension)<=3):
    return False

return True
# return True if s is a valid email, else return False

    def filter_mail(emails): return list(filter(fun, emails))

    if name == 'main': n = int(input()) emails = [] for _ in range(n): emails.append(input())

    filtered_emails = filter_mail(emails) filtered_emails.sort() print(filtered_emails)

    if name == 'main': n = int(input()) emails = [] for _ in range(n): emails.append(input())

    filtered_emails = filter_mail(emails) filtered_emails.sort() print(filtered_emails)
