Is this code in the dropbox documentation right?

Question

from dropbox import Dropbox
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:
    access_token, user_id = auth_flow.finish(auth_code)
except Exception, e:
    print('Error: %s' % (e,))
    return

dbx = Dropbox(access_token)

I got this code from http://dropbox-sdk-python.readthedocs.io/en/master/moduledoc.html#module-dropbox.oauth

Basically what I want to is, test some simple commands. In the beginning of my code I define

APP_KEY = 'mykey'
APP_SECRET = 'mysecret'

Whenever I run the code, give access to my app and put in the authorization code it gives out an error.

NameError: name 'access_token' is not defined

I am using python2.7. There is something wrong with the try/exception part, but I can not figure out what.

Can anyone help?

Perhaps they forgot to add a function there, otherwise `return` statement there is a syntax error. — Ashwini Chaudhary, Dec 08 '16 at 13:20
are you seeing 'Error: ' when you run it? have you tried printing out the results of the auth_flow.finish() call within the try/except? what have you tried? — matias elgart, Dec 08 '16 at 13:22
`return` is used to exit `function`, not program/script. To exit script use `exit()` or use `access_token = None` before `try/except` and `if access_token: dbx = Dropbox(access_token)` — furas, Dec 08 '16 at 14:46

I tried you code and it seems something was changed in code but not in documentation.

Now auth_flow.finish(auth_code) returns object OAuth2FlowNoRedirectResult(), not tuple with access_token, user_id, and this object has properties obj.access_token, obj.user_id, obj.account_id

from dropbox import Dropbox
from dropbox import DropboxOAuth2FlowNoRedirect
import webbrowser

APP_KEY = 'xxx'
APP_SECRET = 'xxx'

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."

webbrowser.open(authorize_url) # open page in browser

auth_code = raw_input("Enter the authorization code here: ").strip()

obj = None

try:
    obj = auth_flow.finish(auth_code)
    #print obj
    #print type(obj)
    #print dir(obj)
    print obj.access_token, obj.account_id, obj.user_id
except Exception, e:
    print 'Error:', e
    #exit()

if obj and obj.access_token:
    dbx = Dropbox(obj.access_token)
    print 'OK'

Is this code in the dropbox documentation right?
