Solve the following python programming problem given the following code:
def readbits(self, bits) : 
    '
        Read the specified number of bits from the stream.
        Returns 0 for bits == 0.
        ' 
    if (bits == 0) : 
        return 0 
if (((self % 8) == 0) and (self._bits_pending == 0)) : 
        return self._read_bytes_aligned ((bits // 8)) 
out = 0 
    masks = self._masks 
    def transfer_bits(x, y, n, t) : 
        '
            transfers t bits from the top of y_n to the bottom of x.
            then returns x and the remaining bits in y
            ' 
        if (n == t) : 
            return (((x << t) | y), 0) 
mask = masks [t] 
        remainmask = masks [(n - t)] 
        taken = ((y >> (n - t)) & mask) 
        return (((x << t) | taken), (y & remainmask)) 
while (bits > 0) : 
        if (self._bits_pending > 0) : 
            assert (self._partial_byte is not None) 
            take = min (self._bits_pending, bits) 
            (out, self._partial_byte) = transfer_bits (out, self._partial_byte, self._bits_pending, take)
