#错误：================== RESTART: D:\learn\python\execise\1.9.py ==================
Traceback (most recent call last):

NameError: name 'self' is not defined
最近学的有点头大，求大神帮忙看一下问题怎么解决，
init两边是两个下划线 首先两个类的init都是前后双下划线。
create错写成creat了
False错写成Fales了
if pos>=paddle_pos and pos<=paddle_中paddle_应为paddle_pos
还有一些小错误，你再看看。
