urwid python module return ImportError while importing

[johny]

Binary package hint: python-urwid

While I try import urwid module I get following error:

ubuntu@ubuntu:~$ python
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)

2) python-urwid:

3) I expect no errors just import module

4) Instead ImportError was raised.
