Tkinter applications are single-threaded, meaning that all GUI updates and event handling occur within the main thread. If you perform long-running operations directly in the main thread, your application will become unresponsive or “freeze” until the operation completes. To avoid this, you need to use threading to offload time-consuming tasks to separate threads.
