How Can I Limit Bullet Firing to One at a Time?

How do I stop more than 1 bullet firing at once?

In the provided code, multiple bullets are fired because the if statement controlling bullet creation does not check if a bullet is already being fired. To fix this and allow only one bullet to be fired at a time, modify the if statement as follows:

<code class="python">    if keys[pygame.K_SPACE] and len(bullets) == 0:</code>

With this adjustment, the if statement will only create a new bullet if there are no bullets currently on the screen. This ensures that only one bullet is fired at any given time.
