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'\xc4\xe3\xba\xc3\r\n\xc4\xe3\xba\xc3\r\n\xc4\xe3\xba\xc3'
{'encoding': 'TIS-620', 'confidence': 0.3598212120361634, 'language': 'Thai'}
你好
你好
你好
b'\xe4\xbd\xa0\xe5\xa5\xbd\r\n\xe4\xbd\xa0\xe5\xa5\xbd\r\n\xe4\xbd\xa0\xe5\xa5\xbd'
{'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'))
