turtle.backward(distance) 参数 distance -- 一个数值 海龟后退 distance 指定的距离,方向与海龟的朝向相反。不改变海龟的朝向。 >>> turtle.position() (0.00,0.00) >>> turtle.backward(30) >>> turtle.position() (-30.00,0.00) turtle.right(
当 Screen 类的方法对应函数被调用时会自动创建一个 Screen 对象。当 Turtle 类的方法对应函数被调用时会自动创建一个 (匿名的) Turtle 对象。 如果屏幕上需要有多个海龟,就必须使用面向对象的接口。 注解 以下文档给出了函数的参数列表。对于方法来说当然还有额外的第一个参数 self,这里省略了。
