python-vlc won't start the player

Ok I solved it on my own.I just had to put an infinite loop in the end,so the player has enough time to run:

while True:
     pass

I prefer:

from time import sleep

sleep(5) # Or however long you expect it to take to open vlc
while player.is_playing():
     sleep(1)

This way, we can return once video is done playing.
