Try wrapping the addition in parends:

>>> print format_string % ( names['John'][:] + names['Jane'][:])
John Doe <jodoe at nowhere>
Jane Doe <jadoe at nowhere>

Without explicit parends, you're doing the equivalent of:

>>> print (format_string % names['John'][:]) + names['Jane'][:]

Yes: it would make more sense if the order of operations were
different, but remember -- "%" and "+" both double as arithmetic
and string operators, but both cases have to share the same
preecedence.
