[Tkinter-discuss] TKinter and Python asyncio

[Bhaskar Chaudhary]

Hi

In a slight modification to your code, I created the asyncio
event_loop in the main thread and passed it as an argument to the
asyncio thread. Now Tkinter won't freeze while the urls are fetched.

I have added the modified code as an answer to your stack overflow
question here:
