This is what doesn't work:

In [8]: print "%s/%s/%s/%s" % ("hi", "there", x())
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

?

TypeError: not enough arguments for format string


But this does:

In [9]: print "%s/%s/%s/%s" % ( ("hi", "there")+ x())
hi/there/a/b


See the difference? you need to build  a _single_ list of 4 elements.
