main lop in python tkinter

[barryjo]

I have some code like this in my tk program..

       root = tk.Tk()

     # (code like entry boxes, labels, functions, etc.)

      root.mainloop()     # the last statement

Specifically I want to continually display my webcam and also to be able to use the buttons, labels, and etc.

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()
 
    # Our operations on the frame come here
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
 
    # Display the resulting frame
    cv2.imshow('frame',gray)
    if cv2.waitKey(1) ==27:
        break

1. What is the function of root.mainloop() ? Is this a never ending loop?
2. How do I insert the other code in this loop that gets called repeatedly?

Please, use proper tags when post code, traceback, output, etc. This time I have added tags for you.
