def ac_encode(text, probs):
coder = Arithmetic()<EOL>coder.set_probs(probs)<EOL>return coder.encode(text)<EOL>
Encode a text using arithmetic coding with the provided probabilities.

    This is a wrapper for :py:meth:`Arithmetic.encode`.

    Parameters
    ----------
    text : str
        A string to encode
    probs : dict
        A probability statistics dictionary generated by
        :py:meth:`Arithmetic.train`

    Returns
    -------
    tuple
        The arithmetically coded text

    Example
    -------
    >>> pr = ac_train('the quick brown fox jumped over the lazy dog')
