databricks pyspark/ python download data from shared url and password

We can't offer help on the Databricks/Pyspark side of this, as that's made by a third party, but to programmatically download file data from a password-protected Dropbox shared link, we recommend using the official Dropbox API v2 Python SDK. Specifically, you can use the sharing_get_shared_link_file method to download file data from a shared link, optionally supplying the password if needed.

That would look like this:

import dropbox

ACCESS_TOKEN = "..."

dbx = dropbox.Dropbox(ACCESS_TOKEN)

shared_link = "https://www.dropbox.com/s/..."
password = "..."

metadata, res = dbx.sharing_get_shared_link_file(url=shared_link, link_password=password)
print(metadata)
print(res.text)

The second variable in the returned tuple is a requests.Response object, which offers a few methods for reading out the file content.
