Confused by "format requires a mapping"

[contact.morrison at gmail.com]

Hello,

I'm very new to Python, and unsure how to handle this runtime error
below. Pointers in the right direction (RTFM here ... etc) most
appreciated.

I have an object, called article, that when printed has the following
structure:

{'title': 'wbk', 'entries': [('http://wbk.opendarwin.org/blog/?p=51',
1), ('http://wbk.opendarwin.org/blog/?p=48', 1),
('http://wbk.opendarwin.org/blog/?p=50', 1),
('http://wbk.opendarwin.org/blog/?p=49',1),
('http://wbk.opendarwin.org/blog/?p=45', 1),
('http://wbk.opendarwin.org/blog/?p=44', 1),
('http://wbk.opendarwin.org/blog/?p=43', 1),
('http://wbk.opendarwin.org/blog/?p=42', 1),
('http://wbk.opendarwin.org/blog/?p=41',1),
('http://wbk.opendarwin.org/blog/?p=40',
1)]}('http://wbk.opendarwin.org/blog/?p=51', 1)
DEBUG: Above was a dump of article, prior to "return
unicode("%(title)s"%article)"

As mentioned in the DEBUG output, my code now returns the following
string:

    unicode("%(title)s"%article)

However, that appears to conflict with article's structure, and i don't
know why? I'm probably missing something fundamental with Python's
syntax?

TIA
Morrison
