I want to develop a backup app, I wish that the app will be able only to upload files without any permissions to delete files (or any other permission).
is it possible ?
Yes, it's possible. Start by looking for a python library that lets you communicate with the Google Drive API. See Google APIs Client Library and PyDrive (you'll find easy code as example here).

I have a bunch of files in a Google Cloud Storage bucket, including some Python scripts and text files. I want to run the Python scripts on the text files. What would be the best way to go about doing this (App Engine, Compute Engine, Jupyter)? Thanks!
I recommend using Google Cloud Function, that can be triggered automatically each time you upload new file to the Cloud Storage to process it. You can see workflow for this in Cloud Function Storage Tutorial
You will need to at least download the python scripts onto an environment first (be it GCE or GAE). To access the GCS text files, you can use https://pypi.org/project/google-cloud-storage/ library. I don't think you can execute python scripts from the object bucket itself.
If it is troublesome to change the python codes for reading the text files from GCS, you will have to download everything into your environment (e.g. using gsutil)
I am pretty new Google app engine, and though I have hacked around with alot of languages, I am finding the google documentation a little overwhelming. I have successfully launched a static site, and successfully run some python code from the console. But I have not run any python from my static site.
I am a Small company trying to setup a google app engine static/dynamic website that I only want to expose to my Gsuite users.
I have some python code I want to run on my app engine, which will download a file from gdrive/teamdrive, process the file, create a new file from the results and then upload the resulting file to the same folder.
I may also at a later date have this static/dynamic website also interfacing with Cloud SQL(mysql) or an external database.
my Questions
What authentication method to use to only expose this website to my gsuite users?
Though I have worked through some of the GDrive api examples whats the best and easiest method of passing GDrive text files to my python code? (though I have hacked around with python lots in the past, the html and python combination perplexes me)
Thanks!
You would use OAuth2.0 to acquire a token which you can then use to interact with that user's files through the GDrive API (see "About Authorization" as well as this quickstart Python example).
I need to export my blobstore from one appengine project and upload it to another project. How can I switch between projects programmatically with python?
If by "python" you mean a python GAE app's code itself - AFAIK you can't switch apps - each such code runs only inside the app specified in the .yaml file.
You could teach the exporting app project to serve the blob and for the actual transfer you could either:
have the receving app directly pulling the blobs from the exporting app
have an external (python) script pull blobs from the exporting apps and uploading them to the importing app.
Either way you'd need to write some code to actually perform the transfer.
So instead of doing that, I'd rather write and execute a one-time conversion script to move the data from blobstore (presently shown in the GAE python docs under Storing Data > Superseded Storage Solutions section on the left-side menubar) to the Datastore or GCS, both of which have better backup/restore options, including across apps :) GCS can probably be even used to share the same data across apps. And you can still serve the GCS data using the blobstore API, see Uploading files directly to Google Cloud Storage for GAE app
If you mean some external python app code - AFAIK the blobstore doesn't offer generic access directly to an external application (I might be wrong, tho). So an external app would need to go through the regular upload/download handlers of the 2 apps. So in this case switching between projects really means switching between the 2 apps' upload/download URLs.
Even for this scenario it might be worthy to migrate to GCS, which does offer direct access, see Sharing and Collaboration
I'm working on an app in django that allows users to upload documents to google drive and share them with friends. The problem is I want to restrict the shared documents to view only (no download option). How can I go about doing this?
You can insert/upload files using the Drive API and set the "restricted" label to prevent downloading of the file. You would then set the appropriate permissions to this file to allow anyone or a specified set of users to access the file.
Download restrictions may or may not apply for files that are converted to one of the Google Apps formats because the option to prevent downloading seems unavailable for these files through the Google Drive UI. You would have to test this yourself.
I'm trying to work out if it is possible to use Google Apps Scripts inside Google App Engine?
And if there is a tutorial in doing this out there ?
Through reading Google's App Script site I get the feeling that you can only use app scripts inside Google Apps like Drive, Docs etc?
What I would like to do is to be able to use the Groups Service that is in GAS inside GAE to Create, delete and only show the groups that a person is in, all inside my GAE App.
Thanks
No you can't. AS and GAE are totally different things and won't work together.
What you can really do is (abstract):
write an AS that does what you need
redirect from GAE to the AS url to make sure that the user logs-in/grants permissions.
perform what you needed to do with AS
send back the user to GAE with a bunch of parameters if you need to
If you need GAE in Google Apps script, you can write a webservice in GAE using UrlFetch in Apps Script: https://developers.google.com/apps-script/service_urlfetch
To give you an example: I created an Apps Script to get report data (json) from an appengine webservice. This data is added to a google apps spreadsheet.
