"""Safely evaluates a string as a Python literal using `ast.literal_eval`.

This function attempts to evaluate the input string as a Python literal. If the initial evaluation fails, it modifies the string to ensure it resembles a dictionary format by adding curly braces and correcting key formatting. If the modified string still cannot be evaluated, the function returns `None`.

Args:
    s (str): The string to be evaluated as a Python literal.

Returns:
    The evaluated Python object (e.g., dict, list, int, etc.) if successful, otherwise `None`.
