Validating UID

    i tried to write the code in a clearer way, using re.VERBOSE, however i am unable to complete the excercise with this. in fact, test 3 fails expecting, for example, string "944A4NKtE2" to be valid (even though the character '4' is repeating). How so? is someone able to help me understand this?

    import re

pattern = re.compile(r"""
    ^
    (?=.*[A-Z]{2,})     # At least 2 uppercase English alphabet characters
    (?=.*\d{3,})        # At least 3 digits
    (?=.*[a-zA-Z\d])    # Only alphanumeric characters
    (?!.*(.).*\1+.*)       # No repeated character
    .{10}
    $
    """, re.VERBOSE)

for _ in range(int(input())):
    correspondence = pattern.search(input())
    if correspondence:
        print("Valid")
    else:
        print("Invalid")
