For efficiency reasons that nb.sobj is not compressed. Do:
sage: pwd
'/Users/was/.sage'
sage: nb = load('sage_notebook/nb.sobj', compress=False)
sage: nb
<class 'sage.server.notebook.notebook.Notebook'>
sage: nb.add_user?
Type: instancemethod
Base Class: <type 'instancemethod'>
String Form: <bound method Notebook.add_user of <class
'sage.server.notebook.notebook.Notebook'>>
Namespace: Interactive
File:
/Users/was/s/local/lib/python2.5/site-packages/sage/server/notebook/notebook.py
Definition: nb.add_user(self, username, password, email,
account_type='user', force=False)
Docstring:
INPUT:
username -- the username
password -- the password
email -- the email address
account_type -- one of 'user', 'admin', or 'guest'
