    Can anyone help, why this doesnt pass all test cases:

    n = int(input()) b = [input() for _ in range(n)] b = "\n".join(b) replacements = [(" && ", "and"), (" || ", "or")] [b := b.replace(x, y) for x, y in replacements] print(b)

    import re,sys

data = sys.stdin.read().splitlines()
remaining = "\n".join(data[1:])
print(re.sub(r'(?<= )([&]{2}|[|]{2})(?= )',lambda x:"and" if x.group(1)=="&&" else "or",remaining))
