How can i combine three ffmpeg command in python?

Question

I want to combine three ffmpeg commands on my video and I want single output. In the following code I give a video(footage) as input and I want to compress my video, add watermark and also display frame numbers on the video and after executing these commands it gives an output video. How can I combine these commands?

f'''ffmpeg -i {footage} -vcodec libx264 -acodec aac \ "drawtext=text='{hostname}\n {socket.gethostbyname(hostname)}\n {getpass.getuser()}':x=10:y=H-th-10:fontfile=KhmerOS.ttf:fontsize=50:fontcolor=black:shadowcolor=black:shadowx=2:shadowy=2 " \ "drawtext=fontfile=KhmerOS.ttf: text='%{{frame_num}}': start_number=1: x=(w-tw)/2: y=h-(2*lh): fontcolor=black: fontsize=50: box=1: boxcolor=white: boxborderw=5" -c:a copy {mov_path} '''
