Why is tf.Variable uppercase but tf.constant lowercase?

Question

There is a little hard to guess why the case (I mean, upper case versus lower case) of constructors for variable, placeholder and constant is not the same, as below: tf.Variable(), tf.placeholder(), tf.constant().

What is the inherent difference between the variable method and the rest, that is start with an upper case letter?

Someone downvoted this without comment, so I upvoted it with this comment. I would also like to know whether there is a reason for this or if it's just different people doing different modules within tensorflow. — The Puternerd, Apr 21 '17 at 07:01

tf.constant() and tf.placeholder() are nodes in the graph (ops or operations). On the other hand tf.Variable() is a class.

And in PEP8 python style guide:

Class names should normally use the CapWords convention.
