Serve a txt file programmatically with gae python

I know that I can't write files into the google app engine system, but I wonder if from the datastore I could programmatically build a txt file and serve it directly to download to the user of the application. I am not storing the file. I just want to serve it.

Any idea if this is possible?

Yes, it's possible. You need to set the header to indicate that the file must be an attachment.

class MainHandler(webapp2.RequestHandler): 
    def test_download(self):
        self.response.headers.add_header('content-disposition','attachment',filename='text.txt')                 

        self.response.write("hello world")

You can see more information looking at the source for webapp2

Regarding "can't write files into the google app engine system", you can write to the blobstore instead. So if you need to generate a large file, you write it to the blobstore and serve it from there.
