Solve the following python programming problem given the following code:
def __init__(self, samplerate = None, blocksize = 0, device = None, channels = None, dtype = 'float32', latency = 0, callback = None, finished_callback = None, **flags) : 
    (parameters, self.dtype, samplerate) = _get_stream_parameters ('output', device, channels, dtype, latency, samplerate) 
    self.device = parameters.device 
    self.channels = parameters.channelCount 
    def callback_wrapper(iptr, optr, frames, time, status, _) : 
        data = _frombuffer (optr, frames, self.channels, self.dtype) 
        return callback (data, _time2dict (time), status) 
_StreamBase.__init__ (self, ffi.NULL, parameters, samplerate, blocksize, (self and callback_wrapper), finished_callback, ** flags) 

    
    

    Fix the buggy line: _StreamBase.__init__ (self, ffi.NULL, parameters, samplerate, blocksize, (self and callback_wrapper), finished_callback, ** flags)

#Here is Python program to fix the buggy line: _StreamBase.

_StreamBase.__init__ (self, ffi.NULL, parameters, samplerate, blocksize, (callback and callback_wrapper), finished_callback, ** flags)
