STR that should be file?

[j2]

Ok, as my code clearly demonstrates, i am a blatant newbie.. but i cant
figure this out. Traceback at the bottom (Python 2.2 on win32)  Help?


from ftplib import FTP
import sys
import ConfigParser
ftpsite = 'ftpeur.nai.com'
directory ='/pub/antivirus/datfiles/4.x/'
updateini = 'update.ini'
tempdir = 'c:\\naitemp\\'

# This will handle the data being downloaded
# It will be explained shortly
def handleDownload(block):
    file.write(block)
    print ".",

#COde to fetch a file, and write it to disk
def getFile(Path, Name, Destination):
    ftp = FTP(ftpsite)
    try:
        print ftp.login()
    except:
        print "Unable to log on to FTP"
        sys.exit(1)
    try:
        print 'Changing to ' + Path
        ftp.cwd(Path)
    except:
        print "Unable to CWD"
        sys.exit(5)
    #Try fetiching the file
    print "Saving file to " + tempdir + Destination
    file = open(tempdir + Destination, 'wb')
    print "Getting " + Name
    ftp.retrbinary('RETR ' + Path + Name , handleDownload)
    print 'Closing file ' + Name
    file.close()
    ftp.close()

getFile(directory,'update.ini','update.ini')


THis gives me
