Within the game loop of your code, we can firstly get the status of the keyboard and store it in a variable called user_input. We can then check this for certain keys:
user_input = pygame.key.get_pressed()
if(user_input[pygame.K_UP]):
Y=Y-1
elif(user_input[pygame.K_DOWN]):
Y=Y+1
elif(user_input[pygame.K_LEFT]):
X=X-1
elif(user_input[pygame.K_RIGHT]):
X=X+1
If these variables are used to draw something to the screen, then the object will move around the screen.
The alternative way of doing this is within the pygame.events:
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit(); #sys.exit() if sys is imported
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT:
X+X-1
elif event.key == pygame.K_RIGHT:
X=X+1
elif event.key == pygame.K_UP:
Y=Y-1
elif event.key == pygame.K_DOWN:
Y=Y+1
