Published to web does not currently support Python....

[Karam]

My organization has premium accounts and utilizes a lot of python visualizations which are needed to be published to public and client domains... The issue is obvious... We currently have visualizations for R and Python enabled. The visuals work fine in desktop and workspace published environment...
