To follow up on Option 1, you will need some code like this:

    keyPressedTuple = pygame.key.get_pressed()
           
    if keyPressedTuple[pygame.K_a]:  # moving left
        #  whatever you want to do here

    if keyPressedTuple[pygame.K_d]:  # moving right
        #  whatever you want to do here

    if keyPressedTuple[pygame.K_w]:  # moving up
        #  whatever you want to do here

    if keyPressedTuple[pygame.K_s]:  # moving down
        #  whatever you want to do here 

But this code should NOT be inside the for loop that handles events, because this is not based on events.  Instead, this code checks the state of the keyboard every time through your main loop.
