Solve the following python programming problem given the following code:
def extract(method, fileobj, keywords = DEFAULT_KEYWORDS, comment_tags = (), options = None, strip_comment_tags = False) : 
    'Extract messages from the given file-like object using the specified
    extraction method.

    This function returns tuples of the form ``(lineno, message, comments)``.

    The implementation dispatches the actual extraction to plugins, based on the
    value of the ``method`` parameter.

    >>> source = b\'\'\'# foo module
    ... def run(argv):
    ...    print(_(\'Hello, world!\'))
    ... \'\'\'

    >>> from babel._compat import BytesIO
    >>> for message in extract(\'python\', BytesIO(source)):
    ...     print(message)
    (3, u\'Hello, world!\', [], None)

    :param method: an extraction method (a callable), or
                   a string specifying the extraction method (.e.g. "python");
                   if this is a simple name, the extraction function will be
                   looked up by entry point.
if it is an explicit reference
                   to a function (of the form ``package.module:funcname`` or
                   ``package.module.funcname``), the corresponding function
                   will be imported and used
    :param fileobj: the file-like object the messages should be extracted from
    :param keywords: a dictionary mapping keywords (i.e. names of functions
                     that should be recognized as translation functions) to
                     tuples that specify which of their arguments contain
                     localizable strings
    :param comment_tags: a list of translator tags to search for and include
                         in the results
    :param options: a dictionary of additional options (optional)
    :param strip_comment_tags: a flag that if set to `True` causes all comment
                               tags to be removed from the collected comments.
    :raise ValueError: if the extraction method is not registered
    ' 
    func = None 
    if callable (method) : 
        func = method 
else : 
        if...
