python - 为什么在首行定义了utf-8，还要用sys再set一次？

Question

代码如下：

#-*- coding:utf-8 -*-

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

为什么已经写了#-*- coding:utf-8 -*-
下面还要sys.setdefaultencoding('utf-8')
求教？谢谢

这里说的挺明白的：也谈 Python 的中文编码处理

Answer 1

The above one refers to the encoding of this file. The root python sys has nothing to do with it.

Answer 2

Why we need sys.setdefaultencoding(“utf-8”) in a py script?

Answer 3

You can import sys in python. Then use sys.getdefaultencoding() to see what the default encoding of your python is. Anyway, my default is ascii...
By the way, I used the lines of your code on Ubuntu yesterday, and the Chinese output to the command line is still garbled... slightly Weird... In the end, I processed Chinese directly in the file
