# 1. Create variables as a tensor
a = tf.constant(2, tf.int32)
b = tf.Variable(10, tf.float32)

# 2. Write opertaions between them
c = tf.multiply(a, b)

# 3. Initialize variables
init = tf.global_variables_initializer()

# 4. Create and run a Session
with tf.Session() as sess:
    sess.run(init)
    sess.run(c)
