字符编码格式检测 cchardet 探索

cchardet是一种高速通用字符编码检测器，支持多种编码

 pip install cchardet

出现报错，从报错信息上看我的电脑缺少 Microsoft Visual C++ 14.0

error: subprocess-exited-with-error

可以按照需求选择需要的模块安装，这里我直接选择第一个完整的安装

等待安装完后重启

再次pip安装成功

新建一个txt，随便输入点字符

将官网示例改成自己的

# -*- coding: utf-8 -*-
import cchardet as chardet 
with open(r"test.txt","rb") as f:
	msg=f.read()
	result=chardet.detect(msg)
	print(result)

检测成功

另存为ANSI

再次检测

看来不是很好用
