Python strings are immutable; methods like decode() create a brand new
string for you. What your program 2 version does is to name the string of
hex digits "newdata", decode it as hex into a new string and then throw
that new string away. Your program 1 version by contrast decodes the
string of digits as hex and then names is "newdata", throwing the original
string of digits away
Thanks for the reply James.
How can I make my program 2 look like program 1 , any hacks ? because I
get newdata value( as a hx return value Of type string )from a function.
