python 处理string到hex脚本的方法

#!/usr/bin/env python# -*- coding:utf-8 -*- from sys import argv script,first = argv  buf = []tmp = [] #读取待处理文件全部内容 并存到buf中with open(first, 'r') as f: buf = f.read()f.closed #对buf中内容，进行每隔2个字符取出，并以", 0X"连接，最后在头部加上'0X'for i in range(0,len(buf),2):  tmp.append(buf[i:i+2])hex_temp = ", 0X".join(tmp)hex_buf = '%s%s' %('0X', hex_temp) #把处理后的hex数据写入到hex.txt文件中with open("hex.txt", 'w') as out: out.write(hex_buf)out.close()
