A developer uses re.match() to validate email addresses in a list. Some invalid entries pass validation. What is wrong?

Code

import re

emails = ["user@example.com", "user@example.com INVALID", "bad@"]

for email in emails:
    if re.match(r"[\w.]+@[\w.]+\.\w+", email):
        print(f"valid: {email}")
    else:
        print(f"invalid: {email}")

import re emails = ["user@example.com", "user@example.com INVALID", "bad@"] for email in emails: if re.match(r"[\w.]+@[\w.]+\.\w+", email): print(f"valid: {email}") else: print(f"invalid: {email}")
