You can'ty since the reasoin the files are read-only is to prevent 
them
being over-written or deleted! You need to convert them from read-only
and then delete them. Its not too hard provided you have the relevant
access rights to change mode.

You can only do from Python what you can do from the OS.
If you don't have access to the files from the OS you won't have 
access
from Python - thats why access rights are there!

For more on how to do it we need to know your OS, since this is
almost certainly a job for the OS rather than Python, unless you
want to do more than just delete the files.

If you do have access rights then you can find out all the needed
steps in the OS topic in my tutor.
