Issue with multi keys being pressed at once for two player game

I am not sure if it is my coding or just my computers limitations but I seem to have issue with multiple keys being pressed in a two player game. The keys themselves work correctly and as I want them too, but since two players could be pressing 4 keys simultaneously (say W, A, UP and LEFT) if they are both speeding forward and want to dodge something left or right, it seems that one of the keys will not work for one of the players if all 4 are being pressed at same time.... 'left' (A) will suddenly work if player1 releases 'up' (W) - this is while simultaneously player2 is pressing 'up' (UP) and say right (RIGHT)

Is there a better way to ask for key event / pressed for this to stop happening or is my code ok and maybe my computer is just lagging?

keystate1 = pygame.key.get_pressed()
if keystate1[pygame.K_a]:
    self.speedx = -5
if keystate1[pygame.K_d]:
    self.speedx = 5
if keystate1[pygame.K_w]:
    self.speedy = -5
if keystate1[pygame.K.s]:
    self.speedy = 5

Same would go for player2 except [K.LEFT, K.RIGHT, K.UP, K.DOWN]

Any help would be appreciated

Upon further testing it only seems to happen to player1 pressing A when both player1 & player2 are pressing up (W & UP) at same time... then player1 won't move left unless player1 lets go of W or player2 lets go of UP. It doesn't affect player2 at all (UP, DOWN, LEFT, RIGHT) or any other direction of player1 except left A?

This is a hardware limitation of your keyboard. Most of them will not be able to register 4 non-modifier keys being pressed at the same time due to the way they are manufactured
