python中字符串（十六进制和常规）和字节流互转处理

源码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import binascii

def test():
    print("方法一处理...")
    db = b'859859843905894-000-x34x33x32x31x30-ABC-abc'
    #2进制字节流转16进制可见字符串转
    dhs = str(binascii.b2a_hex(db), 'utf-8').upper()
    print(dhs, type(dhs))
    #16进制字符串转2进制字节流
    db = binascii.a2b_hex(dhs)
    print(db, type(db))
    #字节流转utf-8字符串
    das = str(db, 'utf-8')
    print(das, type(das))
    #utf-8字符串转字节流
    db = bytes(das, 'utf-8')
    print(db, type(db))
    
    print("nn方法二处理...")
    db = b'859859843905894-000-x34x33x32x31x30-ABC-abc'
    print(db, type(db))
    das = db.decode('ascii')
    print(das, type(das))
    dus = db.decode('utf-8')
    print(dus, type(dus))
    
    dab = das.encode('ascii')
    dub = dus.encode('utf-8')
    print(dab, type(dab))
    print(dub, type(dub))
    
if __name__ == '__main__':
    print("begin...")
    test()
    print("end")
