python读取文件编码转换问题

encode(编码)   decode(解码)   encoding(编码格式)

#-*- coding:utf-8 -*-
import chardet   #用于查看编码

with open("d:/kk/kk.txt", "rb") as temp:
    tem = temp.read()
print(tem)
print(chardet.detect(tem))
print(tem.decode(encoding="gb2312"))
print((tem.decode(encoding="gb2312")).encode("utf-8"))
print(chardet.detect((tem.decode(encoding="gb2312")).encode("utf-8")))

结果：

b'xc4xe3xbaxc3
xc4xe3xbaxc3
xc4xe3xbaxc3'
{'encoding': 'TIS-620', 'confidence': 0.3598212120361634, 'language': 'Thai'}
你好

b'xe4xbdxa0xe5xa5xbd
xe4xbdxa0xe5xa5xbd
xe4xbdxa0xe5xa5xbd'
{'encoding': 'utf-8', 'confidence': 0.99, 'language': ''}

 其它编码转换：

aa = "\u672c\u7248\u672c\u5185\u4e0d\u652f\u6301\u7684\u63a5\u53e3\u6216\u8005\u63a5\u53e3\u5df2\u7ecf\u88ab\u5e9f\u5f03\uff0c\u8bf7\u53c2\u8003\u8be5\u63a5\u53e3\u7684\u6587\u6863\u3002"
print(type(aa))
print(aa.encode('utf-8').decode('unicode_escape'))
