Try Like this

import re

T = int(input()) invalid_repeats = ['++', '**', '??', '+', '+', '?', '?', '+?', '??']

for _ in range(T): S = input().strip()

# Basic invalid pattern check
is_invalid = any(rep in S for rep in invalid_repeats)

if is_invalid:
    print("False")
    continue

try:
    re.compile(S)
    print("True")
except re.error:
    print("False")

how to solve this code

Accepted solution for python 2

import re
for _ in range(int(raw_input())):
    try:
        re.compile(raw_input().strip())
        print(True)
    except re.error:
        print(False)

With Python3.11, both sample inputs return True.
