What can I do to make my PyGame window respond? - python-3.x

Question

I am trying to make a window open every time I run my code, but every time I run the code, it shows the window as unresponsive.
My code is as follows:
import os
import time
import sys
pygame.font.init()
WIDTH, HEIGHT = 500, 400
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("EscapeGame")
BG = pygame.transform.scale(pygame.image.load(os.path.join("GameMap1.png")), (WIDTH, HEIGHT))
def main():
fps = 60
clock = pygame.time.Clock()
def redraw_window():
WIN.blit(BG, (0,0))
pygame.display.update()
while True:
clock.tick(fps)
redraw_window()
for event in pygame.event.get():
if event.type == sys.exit:
sys.exit()
input()
main()
I've already tried a few thing with event.get and event.pump, I'm probably missing something very basic. Could someone tell me what else I could try?
Also, I'm new at pygame, so if anyone sees another mistake, please tell me about. I would greatly appreciate it.

The window is unresponsive because you don't handle the events by calling pygame.event.get().
While pygame.event.get() is in your code, it's never executed because
a) it's in a function you never call
b) your code blocks on the input() call
You're code should look like this:
import os
pygame.init()
WIDTH, HEIGHT = 500, 400
def main():
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("EscapeGame")
BG = pygame.transform.scale(pygame.image.load(os.path.join("GameMap1.png")).convert_alpha(), (WIDTH, HEIGHT))
fps = 60
clock = pygame.time.Clock()
while True:
clock.tick(fps)
for event in pygame.event.get():
if event.type == pygame.QUIT:
return
WIN.blit(BG, (0,0))
pygame.display.flip()
main()
