Non-UTF-8 code starting with 与 'utf-8' codec can't decode byte 类问题求解 python 3.6

环境 win10 python 3.6

如下代码：

1. sum=0
2. for i in range( 1, 5):
3. for j in range( 1, 5):
4. for k in range( 1, 5):
5. if i!=j and j!=k and i!=k:
6. print(i,j,k)
7. sum+= 1
8. print( "共",sum, "种")

改来改去 报错就是Non-UTF-8 code starting with 与 'utf-8' codec can't decode byte

看了很多的博客都不行，有的还要import sys 比如这个博客

最后还是 在第一行加一个就行 ：# coding=gbk

1. sum=0
2. for i in rang
3. 
   
4. 
   
5. e( 1, 5):
6. for j in range( 1, 5):
7. for k in range( 1, 5):
8. if i!=j and j!=k and i!=k:
9. print(i,j,k)
10. sum+= 1
11. print( "共",sum, "种")
