Possibility of updating?

Question

Python

from time import sleep,time
BUB_CHANCE=10
#MAIN GAME LOOP
while True:
    if randint(1,BUB_CHANCE)==1:
       create_bubble()
    move_bubbles()
    window.update()-обновляет окно,чтобы перерисовать пузыри в новых позициях.
    sleep(0.05)

question - does window.update() update the window only for the bubbles or for all the details? (for example, if I still have another shape and I moved it with the keys, will it return to its original place or stay there?)

Answer 1

The question was asked incorrectly. window - what is it? from which library? custom class?
In general, you need to look at the window.update() code to understand what it does.
