Run Details #675

Question: Write Python 3.12 code only. Define exactly one function named count_target_letter(text, target). Return how many times the target letter appears in the string. Count should be case-insensitive. Raise TypeError for non-string input, and raise ValueError if target is not exactly one character. Do not use any imports (no numpy, requests, or other libraries). Sandbox note: dunder attribute access is blocked (for example, type(x).__name__). Avoid names/attributes starting with '__'. Expected output format: - Return exactly one fenced Markdown code block starting with ```python and ending with ```. - Put only valid Python code inside that block (no prose before/after). - Use 4 spaces for indentation (not tabs). - Do not return JSON and do not wrap code in a "function" key. Sample input/output behavior: - count_target_letter("Mississippi", "s") -> 4 Task: Write a Python 3.12 function for 'how many times does the target letter appear in a string'.

def count_target_letter(text, target):
    """Counts the number of occurrences of the target letter in the string.

    Args:
        text (str): The string to search for the target letter in.
        target (str): The target letter to find.

    Returns:
        int: The number of occurrences of the target letter in the string.

    Raises:
        TypeError: If the input is not a string.
        ValueError: If the target letter is not exactly one character long.
    """

    # Convert the string to lowercase for case-insensitive search.
    text = text.lower()

    # Check if the target letter is in the string.
    if target not in text:
        raise ValueError("Target letter '{}' not found in the string.".format(target))

    return text.count(target)


# Example usage.
