Question

import sys

import pygame


def check_events(ship):

    elif event.type == pygame.KEYDOWN:
        if event.key == pygame.K_RIGHT:
            # Move the ship to the right.
            ship.moving_right = True

    elif event.type == pygame.KEYUP:
        if event.key == pygame.K_RIGHT:
            ship.moving_right = False

def update_screen(ai_settings, screen, ship):
    '''Update images on the screen and flip to the new screen.'''

You can't have an elif without an if. Change the first one to an if. — Selcuk

In your function, your first condition should start with an if.

def check_events(ship):

    if event.type == pygame.KEYDOWN:  # <--- note the change here
        if event.key == pygame.K_RIGHT:
            # Move the ship to the right.
            ship.moving_right = True

    elif event.type == pygame.KEYUP:
        if event.key == pygame.K_RIGHT:
            ship.moving_right = False

You have an elif without an if preceding it. Just change the first elif to an if.

You cannot use elif before an if statement. Elif cannot be used without an if statement. This is the right syntax. import sys

import pygame

def check_events(ship):

if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_RIGHT:
        # Move the ship to the right.
        ship.moving_right = True

elif event.type == pygame.KEYUP:
    if event.key == pygame.K_RIGHT:
        ship.moving_right = False

def update_screen(ai_settings, screen, ship): '''Update images on the screen and flip to the new screen.'''
