Reading a binary file in as hex

[Julio Flores Schwarzbeck]

import string
str = open("binoranydata","rb").read()
hexStr=""
for x in range(0, len(str)):
     hexStr=hexStr+hex(ord(str[x]))+"\n"
print hexStr

If file "binoranydata" has the string "Hola" (w/o quotes), the script will 
print:

0x48
0x6f
0x6c
0x61

on the screen
