I am working on a Raspberry Pi Zero project. Using a 1941 Phil
co Predictatelevision, that I fully refurbished, I want to c
reate some python code toplay a random video with a digital 
touch sensor module.The digital touch sensory module 
is a bit different from a push button,because you can set it
 by some wood or small metal area and push a 'button'that do
esn't appear to be there. Thats important, because I don't want to
modify this antique in any way...Ok, so anyway... I have pyth
on randomizing the files... I have it usingomxplayer to play
 a video... but then python/the linux box just sits therewit
h the video player - not waiting for the next button press until the 
videois completely over.  I thought I could u
se subprocess.Popen instead of os.system, but I haven'tfigur
ed out if that it true - nor the correct syntax to doso.
Anyone wanna look at my code and see if they can help?  Again, the s
etup is Raspberry Pi Zero holds videos... I want the pythons
cript to wait for a button (digtal input device) press, play a random
 videoand then play another random video if I press the butt
on again. (I know, too,that I'll have to put some kill proce
ss code in there... but I figured I'dget to that after I fig
ured out how to wait for next button press prior tovideo end
ing...)  Heres my current code:-----fro
m gpiozero import DigitalInputDevicefrom time import sleep
import osimport randomimport subprocessbutton 
= DigitalInputDevice(21)while True:# Setup Ran
don VideosvideoPath = "/home/pi/Videos/"vide
oList = os.listdir(videoPath)random.shuffle(videoList)
for video in videoList:target = os.path.join(videoPath, vide
o)# Wait for button pressprint("Waiting for butt
on press to start video.")button.wait_for_active()
os.system('omxplayer --aspect-mode stretch "{}" >/dev/null'.form
at(target))#subprocess.Popen('omxplayer --acpect-mode
 stretch "{}" >/dev/null'.format(target))#The
 subprocess was my idea that would let python continue listening... b
ut  #didnt work YET. The os.system does play a video... just
 waits there before#listening again for a button press.
