帮忙读段程序 Python 程序

Question

如下 麻烦帮忙翻译下 ，其中 hexamessage ＝ 2F203030325D353D3839 运行各个步骤后 得到的是什么结果？？？？？ 麻烦给讲讲

if len(hexamessage)==20:
binarymessage = ""
for i in range(0,len(hexamessage),2):
messageByteString = hexamessage[i]+ hexamessage[i+1]
messageByteDecimalValue = hex2dec(messageByteString)
message8to6Bits = dec2bin(messageByteDecimalValue-32,8)
binarymessage += message8to6Bits[2:8]
binarymessageID_with_type = binarymessage[0:26];
各位 麻烦给出 每步的结算结果！！！！

Answer 1

　　运行一下不就知道了。。。

　　其中函数是我搜到的，不知道你怎么写的。

　　base = [str(x) for x in range(10)] + [ chr(x) for x in range(ord('A'),ord('A')+6)]
　　def dec2bin(string_num):
　　num = int(string_num)
　　mid = []
　　while True:
　　if num == 0: break
　　num,rem = divmod(num, 2)
　　mid.append(base[rem])
　　return ''.join([str(x) for x in mid[::-1]])

　　def hex2dec(string_num):
　　return int(string_num.upper(), 16)

　　hexamessage="2F203030325D353D3839"
　　binarymessage=""
　　for i in range(0,len(hexamessage),2):
　　messageByteString = hexamessage[i]+ hexamessage[i+1]
　　print "messageByteString: ",messageByteString
　　messageByteDecimalValue = hex2dec(messageByteString)
　　print "messageByteDecimalValue: ",messageByteDecimalValue
　　message8to6Bits = dec2bin(messageByteDecimalValue-32)
　　print "message8to6Bits: ",message8to6Bits
　　binarymessage += message8to6Bits[2:8]
　　print "binarymessage: ",binarymessage
　　binarymessageID_with_type = binarymessage[0:26];
　　print "binarymessageID_with_type: ",binarymessageID_with_type

Answer 2

结果就是01的二进制字符串
