Python GUI Libraries

So I’ve been following this tutorial series on wxPython lately, and I’ve been wondering about how it compares to other GUI libraries in Python.

Some quick google searching shows me that Tkinter and PyQt5 are 2 of the most popular GUI libraries in Python. Tkinter however, looks a bit outdated in it’s looks. And PyQt5 looks pretty similar to wxPython.

Is there anyone with actual experience of using any of these 3 libraries that could explain their differences from a practical viewpoint? Like where each is actually used in the industry? Or if any are even used at all these days?
