I have made some major changes to your code. I added pygame.quit() after the while loop so that the window will close when running is False. I moved all the keypress events (the events that are called when the arrow keys are pressed or when the space key is pressed or when the escape key is pressed) to inside the if pygame.event == pygame.KEYDOWN block. That way, when you press a key, the program will check which key was pressed. In the up arrow event, I switched y += 10 to y -= 10 because the smaller the y is, the higher the sprite is drawn. In the down arrow event, I switched y -= 10 to y += 10 due to the same reason. I removed the screen.blit(image (x, y) functions from each of the events. It is unnecessary to call the same function multiple times in the same loop. Instead, I called it once after checking for events. At the very end of the loop, I added pygame.display.update() so that the screen will get updated each frame. At the beginning of the while loop, before checking for events, I added window.fill(white) so that everything that was drawn in the previous frames will be cleared. Next, I added a boolean variable called spacePressed which I set to False before the while loop and set to True when the space key was pressed. Then, in the while loop, I checked if spacePressed is equal to True. If it is, the sprite will be drawn. Lastly, I indented your code.
