I've definitely looked into it. I bought, with enthusiasm, a tablet with the first version of Android that supported Python. Installing the necessary pieces, and editing programs both seem to be super awkward, and my beloved Tkinter has not been ported. I know there are ways, but if it's not more convenient than just walking back to my desk and doing it on a PC, then it won't happen.
Also, truth be told, since I got a smartphone, the muses just haven't spoken to me with an idea of something to script, that's interesting enough to capture my attention.
Lack of a decent keyboard and editor are barriers for me. I need a larger screen simply to see what I'm doing, in my old age. And most of what I do with scripting, nowadays, has to do with things that are not on my phone anyway, such as processing big files and interacting with measurement instruments.
What's happened instead is that I got a tablet with an OS that's scriptable, and that has a detachable keyboard. Now, all I have to do is wait for those damn muses to speak up. ;-)
