Solve the following python programming problem given the following code:
@ classmethod 
def from_docopt(cls, doc, inputs = None, outputs = None, source = None) : 
    "Create Options from a help string using the docopt parser

        The inputs and outputs can be set to options names to
        set a specific type.

        If no input or output options are specified explicitly, options
        named ``input`` are assigned as the default input and options
        named ``output`` are assigned as default output output.

        In addition, the default types are checked and options where the
        default points to ``stdin`` or ``stdout`` are given the type
        ``TYPE_INPUT`` and ``TYPE_OUTPUT`` respectively.

        Here is an example of how an ``Options`` instance can be created from
        a doc string::

            Options.from_docopt('''            usage:
                tool -i <input>
            options:
                -i, --input <input>  the input option
            ''')

        :param parser: the argparse instance
        :param inputs: list of names of ``TYPE_INPUT`` options
        :param output: list of names of ``TYPE_OUTPUT`` options
        :returns: a new Options instance
        :rtype: :class:`Options`

    doc = doc.replace ('\t', '    ') 
    inputs = ([re.sub ('^-*', '', s) for s in inputs] if inputs else [])

    opts = cls (source = source) 
    opts._help = doc

    if (len (usage_sections) == 0) : 
        log.debug ('No usage section found') 
        return opts 
if (len (usage_sections) > 1) : 
        raise ValueError ('More than one "usage:" (case-insensitive).') 
opts._usage = s [0] 
    def to_name(pattern) : 
        'Convert pattern name to option name' 
        name = pattern.name 
        if name.startswith ('<') : 
            name = name [1 : (- 1)] 
else : 
           ...

    
    

    Fix the buggy line: opts._usage = s [0]
assistant
#Here is Python code to fix the buggy line: opts.

opts._usage = usage_sections [0]
