There are some issues in your code, but the most obvious thing is that you are loading the image into the application loop. pygame.image.load is very time consuming, because it has to read the images from the data store.

Load the image once before the application loop, rather than continuously in the loop:

sky=pygame.image.load("sky.jpg")      # <--- ADD

running=True
while running:
    # [...]

    # sky=pygame.image.load("sky.jpg")  <--- DELETE

ok thanks it is working now – Teerth Sonawani Jan 25 '21 at 13:12 — Teerth Sonawani, Jan 25 '21 at 13:12
