Tensorflow using Python programming

Question

I'm really newbie in python programming specially in tensorflow concept, I already installed tensorflow in my PC, But when I make a simple program to execute "Hello Tensorflow" there is something annoyed me, the out put always appear " b' " like this picture. Error Image and my source code like this:

import tensorflow as tf
hello = tf.constant("Hello, TensorFlow!")
sess = tf.Session()
print(sess.run(hello))

anybody may help me to solve this problem please? I'm sorry for my bad english anyway. Thanks

In python 3 there are two types of strings.

byte strings
strings

byte strings are array of characters which are prefixed by b'. In order to convert byte into string one needs to decode it. byte instances have method decode that will convert the byte to normal string. decode method expects encoding usually 'utf-8'.

import tensorflow as tf
hello = tf.constant("Hello, TensorFlow!")
sess = tf.Session()
print(sess.run(hello).decode("utf-8"))
