# Import `tensorflow`
import tensorflow as tf
import os

# Initialize two constants
x1 = tf.constant([1,2,3,4])
x2 = tf.constant([5,6,7,8])

# Multiply
result = tf.multiply(x1, x2)

# Print the result
print(result)

# Intialize the Session
sess = tf.Session()

# Print the result
print(sess.run(result))

# Close the session
sess.close()

#Or you can run the session like so:
with tf.Session() as sess:
  output = sess.run(result)
  print(output)

    
y1=tf.constant(5)
y2=tf.constant(6)
result=tf.multiply(y1, y2)
sess=tf.Session()
print(sess.run(result))
sess.close()

#or

with tf.Session() as sess:
    print (sess.run(result))
    
#this closes the session automatically

#try this:
with tf.Session() as sess:
    output=sess.run(result)
    print (output)
    
print (output)
#you can't run sess.run(result) outside of the with action
