    r"""Search student output for a pattern.

    Among the student and solution process, the student submission and solution code as a string,
    the ``Ex()`` state also contains the output that a student generated with his or her submission.

    With ``has_output()``, you can access this output and match it against a regular or fixed expression.

    Args:
        text (str): the text that is searched for
        pattern (bool): if True (default), the text is treated as a pattern. If False, it is treated as plain text.
        no_output_msg (str): feedback message to be displayed if the output is not found.

    :Example:

        As an example, suppose we want a student to print out a sentence: ::

            # Print the "This is some ... stuff"
            print("This is some weird stuff")

        The following SCT tests whether the student prints out ``This is some weird stuff``: ::

            # Using exact string matching
            Ex().has_output("This is some weird stuff", pattern = False)

            # Using a regular expression (more robust)
            # pattern = True is the default
            msg = "Print out ``This is some ... stuff`` to the output, " + \\
                  "fill in ``...`` with a word you like."
            Ex().has_output(r"This is some \w* stuff", no_output_msg = msg)

    """
    if not no_output_msg:
        no_output_msg = "You did not output the correct things."
