My issue

When I’m pressing the “Debug my code” button, I’m getting a blank screen instead of seeing the failed test case.

My code

import re

t = int(input())

for _ in range(t):
    s = input()
    
    valid = "YES"
    # lower case characters should be present
    x = re.search("[a-z]", s)
    if not x:
        valid = "NO"
    
    #number of characters is more than 9
    if len(s) < 10:
        valid = "NO"
    
    # Digits are strictly inside all the other characters
    y = re.search("\D+[0-9]\D+", s)
    if not y:
        valid = "NO"
    
    # Must have one uppercase character strictly inside
    z = re.search(".+[A-Z].+", s)
    if not z:
        valid = "NO"
    
    # Must have one of the given special characters, strictly inside
    a = re.search(".+[@#%&?].+", s)
    if not a:
        valid = "NO"
    
    print(valid)

No, not happening anymore. Not sure what caused it in the first place.
