decode_var(obj: Any, pickle_or_dill: str = 'dill', base: str = 'base64', str_decode: str | None = None) -> Any
    Decode a Python object that was encoded using either the 'pickle' or 'dill' library,
    and then decode the baseXX encoded result.
    
    Parameters:
        obj (str or bytes): The encoded object to be decoded.
        pickle_or_dill (str, optional): The library to be used for decoding.
            Valid options are 'pickle' or 'dill'. Defaults to 'dill'.
        base (str, optional): The base encoding used in the encoded object.
            Defaults to 'base64'.
        str_decode (str, optional): The string encoding used after baseXX encoding.
            If None, no additional string decoding is performed. Defaults to None.
    
    Returns:
        object: The decoded object.
    
    Example:
        import numpy as np
        obj = np.array([23, 34, 4])
        a1 = encode_var(obj, pickle_or_dill="dill", base="base64", str_encode=None)
        a2 = encode_var(obj, pickle_or_dill="dill", base="base64", str_encode="utf-8")
        a3 = decode_var(a1, pickle_or_dill="dill", base="base64", str_decode=None)
        print(a3)
        a4 = decode_var(a2, pickle_or_dill="dill", base="base64", str_decode="utf-8")
        print(a4)

encode_var(obj: Any, pickle_or_dill: str = 'dill', base: str = 'base64', str_encode: str | None = None) -> str | bytes
        Encode a Python object using either the 'pickle' or 'dill' library, and then encode the result using baseXX encoding.
    
        Parameters:
            obj (object): The object to be encoded.
            pickle_or_dill (str, optional): The library to be used for encoding.
                Valid options are 'pickle' or 'dill'. Defaults to 'dill'.
            base (str, optional): The base encoding to be used.
                Defaults to 'base64'.
            str_encode (str, optional): The string encoding to be used after baseXX encoding.
                If None, no additional string encoding is performed. Defaults to None.
    
        Returns:
            str or bytes: The encoded object. If 'str_encode' is None, a bytes object is returned.
                Otherwise, a string object is returned.
    
        Example:
            obj = np.array([23, 34, 4])
            >>> a1 = encode_var(obj, pickle_or_dill="dill", base="base64", str_encode=None)
            >>> print(a1)
