Solve the following python programming problem given the following code:
def Parse(controls, * options) : 
    'Parses a control block.

  >>> controls = Parse(\'2 .,+2 regex 4.02s\')
  >>> (controls[\'buffer\'], controls[\'mode\'], controls[\'delay\'])
  (2, \'regex\', 4.02)
  >>> (controls[\'range\'][0], controls[\'range\'][1](1))
  (\'.\', 3)

  >>> controls = Parse(\'1 2\', OPTION.BUFFER, OPTION.DELAY)
  >>> (controls[\'buffer\'], controls[\'delay\'])
  (1, 2.0)

  >>> controls = Parse(\'1 2\', OPTION.DELAY, OPTION.BUFFER)
  >>> (controls[\'buffer\'], controls[\'delay\'])
  (2, 1.0)

  >>> try: Parse(\'1 2 3\', OPTION.DELAY, OPTION.BUFFER)
  ... except DuplicatedControl as e: e
  DuplicatedControl(\'Duplicated buffer control "3"\',)

  >>> try: Parse(\'regex 4.02s\', OPTION.MODE)
  ... except UnrecognizedWord as e: e
  UnrecognizedWord(\'Unrecognized control word "4.02s"\',)

  >>> Parse(\'STRICT\', OPTION.MESSAGE_STRICTNESS)
  {\'messages\': \'STRICT\'}
  >>> Parse(\'STRICT\', OPTION.SYSTEM_STRICTNESS)
  {\'system\': \'STRICT\'}

  Pass in members of OPTION to restrict what types of words are allowed and to
  control word precedence. If no options are passed in, all are allowed with
  precedence BUFFER, RANGE, MODE, DELAY

  Args:
    controls: The control string to parse.
    *options: The allowed OPTION type for each word (in order of precedence).
  Returns:
    A dict with the controls, with OPTION\'s values for keys. The keys will
    always exist, and will be None if the option was not present.
  Raises:
    ValueError: When the control can not be parsed.

    if (not options) : 
        options = [OPTION.BUFFER, OPTION.RANGE, OPTION.MODE, OPTION.DELAY] 
for option in [o for o in options if (o not in OPTION_PARSERS)] : 
        raise ValueError (("Can't parse unknown control word: %s" % option)) 
parsers = [(o, OPTION_PARSERS.get (o)) for o in options] 
    result = { _ : None for (o, _) in parsers } 
    def Insert(key, val, word) : 
        if (result [key] is not None) : 
            raise DuplicatedControl (option, word) 
result [key] = val 
error = None 
   ...

    
    

    Fix the buggy line: result = { _ : None for (o, _) in parsers }

#Here is Python code to fix the buggy line: result = { _ : None for (o, _) in parsers }
.

result = { o : None for (o, _) in parsers }
