Help moding python script to edit Gcode

[AntaresSky]

Hi,
Thanks for the help!
I gave it a try and this is the message I'm getting in the command prompt window.
I tried moving the Else around on the line a bit but didn't help.

D:\>cd lightburn

D:\lightburn>comment.py test.gc
File "D:\lightburn\comment.py", line 19
else:
^
SyntaxError: invalid syntax

D:\lightburn>

Edit got the else figured out but now have this issue.

D:\lightburn>comment.py test.gc
Traceback (most recent call last):
File "D:\lightburn\comment.py", line 18, in <module>
out.lines.append("(" + line + ")")
NameError: name 'out' is not defined

D:\lightburn>


Thanks
