How to check whether a thread has ended in Python - python-3.x

Question

I am working on my first app, and have been following some tutorials on how to setup a working GUI with tkinter and python. My application starts by playing a splash screen animation, and once it completes, switches to the "UserSetup" frame. I am still busy trying to re-code the function that plays this video so that I can call upon it as a method (or whatever works). What I wanted to know is, if there is a way to check once the thread which plays this video has stopped? Any other animations played now run concurrently, and I don't want that. I basically want it to only continue with the next set of animations or whatever once the splash screen animation has stopped.
It is quite a bit of code....

I have used is_alive() in the past.. In the form of:
while thread_name.is_alive():
pass
This will wait for the thread to finish before continuing onto the next part of your script.
Hope this helps!
