Do the Chemistry (and other fields) reference apps and the CDF Player come with a WolframAlpha Pro account?
Wolfram|Alpha Pro basically has all the features of the reference apps (although maybe organized differently). Looking on the website (http://www.wolframalpha.com/pro/) I don't see anything about the apps. I don't believe the apps come with Wolfram|Alpha Pro.
The CDF player is always free:
What about the wolfram python client libraries? Does this require a pro account? I am looking for a getting started guide with wolfram cloud and the python library.
