class FallbackExecutor:
    """
    A class for executing a function with fallback mechanisms in case of errors.

    Args:
        primary_executor: The main callable to be executed.
        fallback_executors: A dictionary where keys are exception types and values are the corresponding fallback functions.
        max_attempts: Maximum number of attempts including initial execution.

    Example usage:

    ```python
    def divide(a, b):
        return a / b

    def safe_divide(a, b):
        try:
            return a / b
        except ZeroDivisionError:
            print("Caught division by zero error. Returning None.")
            return None

    fallback_executor = FallbackExecutor(
        primary_executor=divide,
        fallback_executors={
            ZeroDivisionError: safe_divide
        },
        max_attempts=3
    )

    result = fallback_executor.execute(10, 2)
    print(result)  # Expected output: 5.0

    result = fallback_executor.execute(10, 0)
    print(result)  # Expected output: None (due to fallback function being called)
