I am using Python 2.7.3 and I am writing a script which prints the hex byte values of any user-defined file. It is working properly with one problem: each of the values are being printed on a new line. Is it possible to print the values with spaces instead of new lines?

For example, instead of

61 62

I would like to have 61 62.

Below is my code (..txt is a file which contains the text 'abcd'):

#!usr/bin/python 

import os 

import sys 

import time 

filename = raw_input("Enter directory of the file you want to convert: ") 

f = open(filename, 'rb') 

fldt = f.read() 

lnfl = len(fldt) 

print "Length of file is", lnfl, "bytes. " 

orck = 0 

while orck < lnfl: 

   bndt = hex(ord(fldt[orck])) 

   bndt = bndt[-2:] 

   orck = orck + 1 

   ent = chr(13) + chr(10) 

   entx = str(ent) 

   bndtx = str(bndt) 

   bndtx.replace(entx, ' ') 

   print bndtx

The below-mentioned code does almost everything you want:

f = open('data.txt', 'rb') 

while True: 

   char = f.read(1) 

   if not char: break 

   print "{:02x}".format(ord(char)),

With data.txt created like this:

f = open('data.txt', 'wb') 

f.write("ab\r\ncd") 

f.close()

Output:-

61 62 0d 0a 63 64

To know more about this you can have a look at the following video tutorial:-
