[英]Python: converting hex values, stored as string, to hex data
(Answer found. Close the topic) (找到答案。关闭主题)
I'm trying to convert hex values, stored as string, in to hex data. 我正在尝试将存储为字符串的十六进制值转换为十六进制数据。
I have: 我有:
data_input = 'AB688FB2509AA9D85C239B5DE16DD557D6477DEC23AF86F2AABD6D3B3E278FF9'
I need: 我需要:
data_output = '\xAB\x68\x8F\xB2\x50\x9A\xA9\xD8\x5C\x23\x9B\x5D\xE1\x6D\xD5\x57\xD6\x47\x7D\xEC\x23\xAF\x86\xF2\xAA\xBD\x6D\x3B\x3E\x27\x8F\xF9'
I was trying data_input.decode('hex')
, binascii.unhexlify(data_input)
but all they return: 我正在尝试
data_input.decode('hex')
, binascii.unhexlify(data_input)
但它们都返回:
"\xabh\x8f\xb2P\x9a\xa9\xd8\\#\x9b]\xe1m\xd5W\xd6G}\xec#\xaf\x86\xf2\xaa\xbdm;>'\x8f\xf9"
What should I write to receive all bytes in '\\xFF' view? 我应该写什么来接收'\\ xFF'视图中的所有字节?
updating : 更新 :
I need representation in '\\xFF' view to write this data to a file (I'm opening file with 'wb') as: 我需要在'\\ xFF'视图中表示,才能将此数据写入文件(我正在用'wb'打开文件),如下所示:
«hЏІPљ©Ш\#›]бmХWЦG}м#Ї†тЄЅm;>'Џщ
update2 更新2
Sorry for bothering. 很抱歉打扰。 An answer lies under my nose all the time:
答案一直在我的眼中:
data_output = data_input.decode('hex')
write_file(filename, data_output) #just opens a file 'wb', ant write a data in it
gives the same result as I need 给出与我所需相同的结果
I like chopping strings into fixed-width chunks using re.findall
我喜欢使用
re.findall
字符串切成固定宽度的块
print '\\x' + '\\x'.join(re.findall('.{2}', data_input))
If you want to actually convert the string into a list of ints, you can do that like this: 如果您想将字符串实际转换为整数列表,则可以这样进行:
data = [int(x, 16) for x in re.findall('.{2}', data_input)]
It's an inefficient solution, but there's always: 这是一个低效的解决方案,但始终存在:
flag = True
data_output = ''
for char in data_input:
if flag:
buffer = char
flag = False
else:
data_output = data_output + '\\x' + buffer + char
flag = True
EDIT HOPEFULLY THE LAST: Who knew I could mess up in so many different ways on that simple a loop? 最后编辑:谁知道我可以在一个简单的循环中以许多不同的方式搞乱? Should actually run now...
实际上应该现在运行...
>>> int('0x10AFCC', 16)
1093580
>>> hex(1093580)
'0x10afcc'
So prepend your string with '0x' then do the above 因此,请在字符串前添加“ 0x”,然后执行上述操作
