I\'m looking for a good samaritan that can provide with a very basic skeleton to run a python script using Google App Engine. I have read the documentation, check on related SO
The answer I mentioned still applies - you won't be able to run your scripts in a standalone manner on GAE cron, simply because the cron service is really just a set of scheduled GET requests. You may be able to achieve the same end result, but by:
You can find a Python 3 skeleton in Quickstart for Python 3 in the App Engine Standard Environment
Alternatively you could, of course, use an IaaS service instead of GAE, like Google Compute Engine, where you could run your scripts directly, with a traditional cron service.
