Going from (my own, human) memory here...

buf = StringIO.StringIO()

c = Canvas(buf)
c.drawString(100,100, 'Hello world')
c.save()


raw_pdf_content = buf.getvalue()


In Platypus, wherever you would pass in the file name, do the same thing.

A very common use for this pattern is to send files as a response from a
web request without ever saving them to disk.
