Authentication error with Sharepoint API Python Office365 Rest API library

Question

I am trying to connect to Sharepoint using the following code. It was working previously however it has suddenly stopped working, and is now showing the following error:

 File "C:\Users\Documents\Anaconda2\lib\site-packages\office365\runtime\auth\saml_token_provider.py", line 67, in get_authentication_cookie
return 'FedAuth=' + self.FedAuth + '; rtFa=' + self.rtFa

TypeError: cannot concatenate 'str' and 'NoneType' objects

ctx_auth = AuthenticationContext(url)

if ctx_auth.acquire_token_for_user(username, password):

print("Authentication with SharePoint was successful: {0}".format(
        ctx_auth.acquire_token_for_user(username, password)))

ctx = ClientContext(url, ctx_auth)
web = ctx.web
ctx.load(web)
ctx.execute_query()
print "SharePoint Site: {0}".format(web.properties['Title'])

else: print ctx_auth.get_last_error()

It fails on this line:

ctx.execute_query()

I have been using sharepy library as an alternative solution in connecting to Sharepoint.
Use pip install sharepy to install the module.

import sharepy
from sharepy import connect
from sharepy import SharePointSession

server='youraccount.sharepoint.com'
user='[email protected]'
password='password'

s = sharepy.connect(server,user,password) 

# Example request to Sharepoint
headers = {'accept': 'application/atom+json'} #json can be changed to xml
r = s.get("https://youraccount.sharepoint.com/_api/web/GetFolderByServerRelativeUrl('path_to_your_folder/')/Files", headers=headers)

It should print out the following on successful authentication:

Requesting security token...Requesting access cookie... Authentication successful

@YaserSakkaf Yeah, you can generate a client ID and client secret then use that for authentication.
