Incorrect Regex Problem

This Python program is designed to validate regular expressions. It takes an integer input, which represents the number of regular expressions to be tested, followed by the regular expressions themselves. Each regular expression is then compiled using Python's 're' module. If the regular expression is valid, the program prints 'True'; otherwise, it prints 'False'.

Here is the Incorrect Regex Problem HackerRank solution using CodeRankGPT:

The solution works by using Python's built-in 're' module, which provides support for regular expressions. The 're.compile()' function is used to convert the input string into a regular expression object. If the input string is a valid regular expression, 're.compile()' will execute without any issues and the program will print 'True'. However, if the input string is not a valid regular expression, 're.compile()' will raise an exception, which is caught by the 'except' block, and the program will print 'False'.


import re

n = int(input())
for _ in range(n):
    s = input()
    try:
        re.compile(s)
        print(True)
    except Exception as e:
        print(False)
