Which output file(s) do you mean, temp.orc or temp.sco or both?

To the same file? There was a long thread on updating text files very
recently.

Have you considered deploying a spelling checker?

Why the obfuscation?

and which is line 14?? According to my count, it is the blank line
after "outfile2 = open('temp.orc', 'w') "!!

infile is not used

and how many lines were there in data when you printed it?

Consider the possibility that fromline >= toline (which may be caused
by either or both not being of a numerical type).
Did you mean range(fromline, toline + 1) ?
do this:
print repr(fromline), type(fromline)
print repr(toline), type(toline)
BTW, print is a *statement*, not a function!

outfile.writeline() ???

So, the body of your loop wasn't executed (or you overlooked the
exception, or that wasn't the code that was executed) -- so it looks
like the range was empty (or the problem occurred further upstream).

and what does this do?? Read temp.orc and/or temp.sco before you've
closed the file(s)?
Where is the code that was used to call this playscoreinrange function?
