一行代码生成Redis通信协议的命令，所有命令都行

"".join(reduce(lambda i1,i2:i1+i2 ,[["*",str(len(argv)),"\r\n"]] + [["$",str(len(p)),"\r\n",p,"\r\n"] for p in map(str,argv)]))

搞定，如果加个头定义成函数就两行：

def parseCommand(*argv):
return "".join(reduce(lambda i1,i2:i1+i2 ,[["*",str(len(argv)),"\r\n"]] + [["$",str(len(p)),"\r\n",p,"\r\n"] for p in map(str,argv)]))

只需要 parseCommand("GET","MY-KEY") 就可以输出
*2\r\n$3\r\nGET\r\n$6\r\nMY-KEY\r\n
