Exercise

Defining variables

Unlike a constant, a variable's value can be modified. This will be quite useful when we want to train a model by updating its parameters. Constants can't be used for this purpose, so variables are the natural choice.

Let's try defining and working with a variable. Note that Variable(), which is used to create a variable tensor, has been imported from tensorflow and is available to use in the exercise.
