I intend to build an app that would
1. take user's textual input from a window (just a string of a few characters)
2. use it as an input for a python code
3. output the numeric results into google sheets
I need you to guide me through the app creation process. Bid only if you know how to do it with AWS elastic beanstock, AWS lambda, Google AppEngine, whatever other resources, only if you know the process from the beginning to the end and are able to explain it. Thanks.
