'python raspberry camera settings for night

I have here my perfect setup for my raspberry video.

raspivid -fps 25 -sh 0 -co 50 -br 50 -sa 0 -ISO 800 -ev +2 -ex auto -awb auto -mm average -n -b 2000000 -w 1920 -h 1080 -o /home/pi/cam/nachtvideo.h264 -t 0

Now I have but this fancy python script:

with picamera.PiCamera(resolution='1280x720', framerate=30) as camera:
    output = StreamingOutput()

    camera.brightness = 55
    camera.contrast = 75
    camera.sharpness = 0
    camera.saturation = 0
    camera.iso = 800
    camera.exposure_mode = 'auto'
    camera.start_recording(output, format='mjpeg')

Does someone know how I can make the same effect just as one liner in the python script? Because if I would run the script I can see only black and everything is really dark..

Thanks for your help.

The values, which the python script passes to the camera are sometimes a little bit different from the ones of the raspivid command. Raising the ISO, the brightness, the saturation and hardcoding a high exposure is sometimes necessary here. When I made a timelapse of my street at night, I had to use the 'verylong' exposure_mode, to make it see anything at all.
