a，b，c都没有定义，当然报错啦

先定义：

1. a = 1
   
2. b = 2
   
3. c = 3

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

1. Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) [MSC v.1916 32 bit (Intel)] on win32
   
2. Type "help", "copyright", "credits" or "license()" for more information.
   
3. >>> a , b , c = 1 , 2 , 3
   
4. >>> a < b < c
   
5. True
   
6. >>>
