You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.

Upload session api creating empty files

I see from your code that you're only sending data with the append call. You can actually send data on any/all of the start, append, and finish calls, though it's not required. (Also, for small uploads like this, you don't need to use upload sessions at all, but I presume this is just for the sake of testing the code during development.)
Anyway, you are sending data with the append call, but you aren't checking if that call is succeeding. You should check the result and add some error handling around the append call. You can check success via the returned status code, and check the response body for more information.
I suspect the underlying issue is due to your "offset" handling, and is being obscured by the lack of response/error handling for the append call. Specifically, the "offset" you supply should be "The amount of data that has been uploaded so far" (for the upload session overall), not how much you're sending in the current request, as you appear to have in your code with `len(data)`.

Hi Greg
Thanks for your response.
Yes you are right, the issue is with offset only. It is working now. But as per the documentation https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-append , the append method does not have any return value.

It doesn't have a successful return value, but it can raise a number of different errors. You should still check the response for an error. You can check the status code to determine success/failure at a high level, and check the response body for specific error information. With the incorrect code you had, for instance, the body would have contained error information about the incorrect offset.
