Hi Denny,


What kind of error?  Can you show us exactly what the error message looks
like?  As far as I can tell, the code that you've showed us,

    print >>filehandle, "....%d...%s..." % (num,string)

looks syntactically correct to me.  We really need to see why Python
doesn't seem to like it; show us the error message, verbatim, and we can
go from there.

The method you tried above should work.


Alternatively, you can use the 'write' method of a file object. For
example, since 'sys.stdout' is a file object, we can say something like:

###
sys.stdout.write('hello world\n')
###



Talk to you later!
