if 判断条件 ：

      python语句1

elif 判断条件 ：

      python语句2

else：

      python语句3

多重分支，前面的条件如果符合一条，后面的判断都会取消

not or and 

not级别最高

or次之

and最低

not（），先判断（）里，如果是True，结果就是Flase

print不换行

注意缩进

整型（整数）不需要加双引号，加了双引号就是字符串

双引号一定标识字符串

由于是用记事本打开编辑的所以对编码有要求最终保存为utf-8 文件开头对应utf-8   猜测是这个原因，也许我用个正经编辑器就不会这样
