from shareplum.site import Version

username = 'username@domain.com'
password = 'password'
site_name = 'sharepoint_site_name'
doc_library = 'document_library'

authcookie = Office365(site_name, username=username, password=password).GetCookies()
site = Site('https://' +site_name+ ".sharepoint.com/sites/" +doc_library+ '/', version=Version.v365, authcookie=authcookie)

data = {'Title': 'New item', 'Description': 'Description of new item'}
list_name = 'List Name'
