datetime.date.today() returns a date object, not a string.
if the default string conversion is what you want, use str(today) to
convert to a string.
also note that "join" doesn't do what you think it does; "x.join(y)"
joins all members of the sequence y (which must all be strings) using
x as the separator. this gives you a filename like
'.2/work/output10/work/output10/work/output16/work/output1-/work/output10/work/o
utput11/work/output1-/work/output12/work/output19t2/work/output10/work/output10/
work/output16/work/output1-/work/output10/work/output11/work/output1-/work/outpu
t12/work/output19x2/work/output10/work/output10/work/output16/work/output1-/work
/output10/work/output11/work/output1-/work/output12/work/output19t'
which is probably not what you want.
to fix this, you can use +=
myFile = '/work/output1'
myFile += str(today)
myFile += ".txt"
or % formatting:
myFile = '/work/output1%s.txt' % today
(here, "%s" does the str() call for you).
