Malformed authorize_url returned from DropboxOAuth2FlowNoRedirect.start() Python API

I am trying to use the `DropboxOAuth2FlowNoRedirect` example in the Python class docstring. It looks like this:

from dropbox import DropboxOAuth2FlowNoRedirect

auth_flow = DropboxOAuth2FlowNoRedirect(APP_KEY, APP_SECRET)

authorize_url = auth_flow.start()
print("1. Go to: " + authorize_url)
print("2. Click \\"Allow\\" (you might have to log in first).")
print("3. Copy the authorization code.")
auth_code = raw_input("Enter the authorization code here: ").strip()

try:
    oauth_result = auth_flow.finish(auth_code)
except Exception as e:
    print('Error: %s' % (e,))
    return

dbx = Dropbox(oauth_result.access_token)

The resulting `authorize_url` seems to be malformed: it includes "&" instead of just "&", meaning when navigating to it, Dropbox returns an error: unknown field "amp". Is this a bug or am I doing something wrong?

Thanks

Thanks for the report. This issue doesn't seem to reproduce for me though. To help us investigate, can you share:

the version of the Dropbox Python library you have installed
the version of Python you're using
the full output you get

Ah. It is something to do with Jupyter Lab. The URL is fine in the iPython REPL and in Jupyter notebook. I am using the Python dropbox package version 10.1.1 and Python 3.8.2.

If I run this code:

from dropbox import DropboxOAuth2FlowNoRedirect, Dropbox

auth_flow = DropboxOAuth2FlowNoRedirect(APP_KEY, APP_SECRET)
authorize_url = auth_flow.start()

print("1. Go to: " + authorize_url)
print("2. Click \"Allow\" (you might have to log in first).")
print("3. Copy the authorization code.")

auth_code = input("Enter the authorization code here: ").strip()
try:
    oauth_result = auth_flow.finish(auth_code)
except Exception as e:
    print('Error: %s' % (e,))

dbx = Dropbox(oauth_result.access_token)

in a cell within Jupyter Lab, I get the following output (with client ID removed):

1. Go to: https://www.dropbox.com/oauth2/authorize?response_type=code&amp;client_id=REMOVED
2. Click "Allow" (you might have to log in first).
3. Copy the authorization code.
Enter the authorization code here:

Anyway, this isn't a problem for me, now that I know the URL is properly formed outside of Jupyter Lab.

Thanks!
