这个是老python零基础教学第六讲，但是我用的python3.8.5版本的不支持，一直报错。

NameError: name 'a' is not defined a，b，c都没有定义，当然报错啦
先定义：
a = 1
b = 2
c = 3 我擦。我这是..... 好，谢谢了
这么试
a , b , c = 1 , 2 , 3
a < b < c
两行代码分两次输入
Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) on win32
Type "help", "copyright", "credits" or "license()" for more information.
>>> a , b , c = 1 , 2 , 3
>>> a < b < c
True

a , b , c = 1 , 2 , 3
a < b < c
