预览：在我们开始制作我们的第一个程序之前，让我们看一个例子。
To navigate the page using the TAB key, first press ESC to exit the code editor.
stage.set_background("underwater")
sprite = codesters.Sprite("fish")
sprite.set_speed(2)
sprite.move_down(150)
stage.wait(1)
sprite.move_right(50)
sprite.say("Click on me!")
def click():
sprite.say("Hey there Codester!")
sprite.move_up(100)
sprite.turn_right(360)
sprite.move_down(100)
sprite.say("Great job.")
stage.wait(1)
sprite.say("Click submit and next to continue!")
sprite.set_x_speed(5)
sprite.event_click(click)
