For some reason, this code is only working on Pypy3 platform
import re
T = int(input().strip())
for _ in range(T): S= input().strip() if any(op + '+' in S for op in ['*', '+', '?']): print("False") else: try: re.compile(S) print('True') except re.error: print('False')
Doesn't work under Python 3. It only works under pypy 3
Please redo the test here.
