Pygame if event.type == pygame.KEYDOWN() TypeError: 'int' object is not callable

The code is meant to quickly exit pygame by tapping escape.

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN():
            if event.key == pygame.K_ESCAPE:
                running = False
                pygame.quit()
                sys.exit()

This code errors with this:

Message File Name   Line    Position    
Traceback               
    <module>    G:\Code\JonSocket\keyboard.py   19      
TypeError: 'int' object is not callable             

Very similar code works when,

event.type == pygame.QUIT

Is there a difference between pygame.QUIT + pygame.KEYDOWN?

Thanks.

Your problem is in the line

if event.type == pygame.KEYDOWN():

pygame.KEYDOWN is not a function but just an integer constant.

Change it to

if event.type == pygame.KEYDOWN:
