python - Pygame not checking keyevents after another happens -

i moving sprite on x-axis. moving left , right. when press both left , right @ same time stop moving properly.

i trying make when user presses both keys , lets go of one, continue moving in direction still pressed.

weirdly works while holding right , letting go of left. continues moving right.

when hold left , tap right stops moving until press right again.

i commented out ideas had make work, failed me.

i sure simple fix or logic failure on part.

i have worked couple hours on this.

thanks responses ahead of time.

i think need this:

if keypressed[pygame.k_left]:     movement_x = -5 if event.type == pygame.keyup:     if event.key == pygame.k_left , movement_x < 0:         movement_x = 0 if keypressed[pygame.k_right]:     movement_x = 5 if event.type == pygame.keyup:     if event.key == pygame.k_right , movement_x > 0:         movement_x = 0 

and it... hope helps.
