[(x, x) for x in example]

# is the same as:

output = list()
for x in example:
  output.append((x,x))
  
# because each 'x' is an entire set, e.g:
# (1, u'FromFlask', u'file1.ext', u"['file2.ext']", u'WCP', u'WR_HS', u'email@hotmail.com', u'nothing happens', u'2013-01-3009:15:18.628922', u'None')
# you end up with:

[(example[0],example[0]), (example[1],example[1])]

# where example[0] is a set of many values, wtforms just wants one, so we need to pull out just the filename:

output = [(x[2], x[2]) for x in example)

# which should give you:
[(u'file1.ext',u'file1.ext'),(u'file1.ext',u'file1.ext')]
