I'm working with the python socket module, playing around with a udp client I wrote. I dislike how its handling my hex literals. example:
>>> querydns = '\xb9\x1b\x01\x00\x00\x01\x00\x00\x00\x00\x00\x00\x03\x77\x77\x77\x06\x67\x6f\x6f\x67\x6c\x65\x03\x63\x6f\x6d\x00\x00\x01\x00\x01'
>>> querydns
'\xb9\x1b\x01\x00\x00\x01\x00\x00\x00\x00\x00\x00\x03www\x06google\x03com\x00\x00\x01\x00\x01'
>>> replydata
'\xb9\x1b\x81\x80\x00\x01\x00\x06\x00\x00\x00\x00\x03www\x06google\x03com\x00\x00\x01\x00\x01\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0j\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0i\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0\x93\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0g\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0h\xc0\x0c\x00\x01\x00\x01\x00\x00\x00\xd4\x00\x04@\xe9\xb0c'
Notice how it automatically decodes some of the hex into characters? I want to deal with only hex values, no @'s or www's. Is there an easy way to stop this automatic decoding?
you cant really ... you have a few options(sort of)
import binascii
print binascii.hexlify(querydns)
or fake it(it takes more effort to preserve leading zeros)...
print "".join("\\x%s"%(hex(ord(data_byte))[2:]) for data_byte in querydns)
or a combination I guess would work
hexy = binascii.hexlify(querydns)
print "".join("\\x%s"%hexy[i:i+2] for i in range(len(hexy)-1))
You can use it as 'raw' string by putting a 'r' before the string. A raw string is not processed by the python and is taken as it is.
string = r"example string"
