For example i am using pwm, so the example given in read the docs is:

def set_pwm_duty_cycle(self, io_line, cycle):

    if not io_line.has_pwm_capability():
        raise ValueError("%s has no PWM capability." % io_line)
    if cycle < 0 or cycle > 100:
        raise ValueError("Cycle must be between 0% and 100%.")

    duty_cycle = int(round(cycle * 1023.00 / 100.00))

    self.set_parameter(io_line.pwm_at_command, bytearray(utils.int_to_bytes(duty_cycle)))
