When I run the code the window will appear after the code finished and if I add the main loop at the start the code won't run until I close the window. I want the window to update every time I add a label variable in my code. I searched on multiple docs but they all seem to give the same answer and it did not work.

I am so sorry the mainloop was not shown in the code. I have now edited the code.
CodePudding user response：
all you need to do is add these two functions every time you want the window to update
window.update_idletasks()
window.update()
CodePudding user response：
Programs written for event-driven GUI toolkits like tkinter are significantly different from standard Python scripts.
Once you have created a window, filled it with widgets and have initialized global data, you need to start the mainloop.
Without a running mainloop, there is no interaction with the GUI.
In essence, your program consists of a bunch of functions that are called from the mainloop, in response to the user operating controls, or timers expiring.
(I'm leaving out complications like using threading out on purpose for the sake of simplicity.)
I don't think that pyttsx3 was written with event-driven GUIs in mind. So I suspect you will have to run it in a separate thread or process. Both threads and processes have their pros and cons.
If you are using a process to run pyttsx3, you have to explicitly send the data to the GUI process using interprocess communication. On the other hand, the sound collection process cannot interfere with the GUI.
You could probably relatively easily test it separately from the GUI.
If you use threads you might have issues with responsiveness because in CPython only one thread at a time can be executing Python bytecode.
On the other hand, transferring the data to the GUI is trivial since both live in the same address space.
In my experience calling tkinter functions or methods from a second thread is possible if two conditions are met;
- You are using Python 3 and
- the
tclandtkused were built with support for threads enabled.
