This would beat by far the convenience and usability of this 2-in-1 calculator. I would KILL to have this.
In fact, on my laptop, I use the Python REPL as a calculator. I hit Ctrl-T python ENTER. It opens a terminal and I start typing 48*152 ENTER and I see the result. The history of calculations is saved. I can access previous calculations, edit one number and recompute. I see the last 100 lines or so, on one screen.
The only one somewhat usable Python REPL on Android is "Pyonic Python 3 interpreter" but it's clumsy to use as a calculator because it uses the standard alphabetic keyboard so you have to keep switching to the special characters layout to type math operators (-+/...) If this ONE detail would be fixed, and with some minor UI polish I believe it could become more popular than the 2-in-1 calculator...

It never became anything serious but the whole "find people online on not-dating sites just by communicating" is real.
