The Windows GDI calls don't know anything about lists.  There are several
ways to do what you want:

  for i in range(memory):
    dc.TextOut(10, 10+16*i, memory[i])

Of course, that only works if everything fits on one page.  Another
alternative is to let Windows do the splitting, using dc.DrawText with
DT_CALCRECT.  If you try that, DON'T do the split.  Pass the whole string
to dc.DrawText.  It will STILl have to fit on one page.

If you have multiple pages, you will have to count the Y coordinates
yourself and call EndPage/StartPage.

That's why I use reportlab for my printing.
