Tkinter Freezing Despite Threading

I am currently developing a web scanner that continuously scans for vulnerable URLs. I wanted a GUI for my program and thus chose to use tkinter. Currently I am facing a problem wh

Solution 1:

The thread function posted in the question is calling the nonrecursiveURL function directly, before passing it as the thread target.

defthread(value):
   t = threading.Thread(target=nonrecursiveURL(value)) <-- here nonerecursiveURL is being called

To call a function in a different thread, the threading.Thread instance requires a function reference, and an optional list of arguments to be passed to that function.

t = threading.Thread(target=nonrecursiveURL, args=(value,))

now nonrecursiveURL is not called in here, but only passed to the Thread, and will be called in a different thread, when t.start() is called.

You can confirm this issue, by just calling the thread function from Python REPL, leaving Tkinter out of the debugging session.
