Unable to strip \n characters

[aiwarrior]

Hi
Im writing a personal wrapper to the perl script offered by
rapidshare, so that im able to use multiple files and glob pathnames,
but im using a file so i can track and resume any uploading data. The
problem is the lines come with a \n character that im not bein able to
take out,

        files = f.readlines()
        for upload in files:
                upload.strip("\n")
                final_args = "./rsapiresume.pl %s prem user password"
% (upload)
                print upload
                #os.system( final_args )

My upload string still comes with the \n making the system call look
like this:

./rsapiresume.pl filename_to_upload
prem user password

I've already tried replace but it doesn't work either
