  "prompt": "Here's a simple Python programming task:\n\n**Task:** Write a Python function that checks if a given string is a palindrome or not. A palindrome is a word, phrase, number, or other sequences of characters that reads the same forward and backward (ignoring spaces, punctuation, and capitalization).\n\n**Function Signature:**\n```python\ndef is_palindrome(s: str) -> bool:\n    \"\"\"\n    Check if the given string `s` is a palindrome.\n\n    Args:\n        s (str): The input string to check.\n\n    Returns:\n        bool: True if `s` is a palindrome, False otherwise.\n    \"\"\"\n```\n\n**Example:**\n\n```python\nassert is_palindrome(\"racecar\") == True\nassert is_palindrome(\"hello\") == False\nassert is_palindrome(\"A man, a plan, a canal: Panama\") == True  # Ignoring spaces and punctuation\n```\n\n**Hint:** You can use the `str.lower()` method to convert the string to lowercase and the `re` module to remove non-alphanumeric characters.",
