How to download a file via FTP with Python ftplib

handle = open(path.rstrip("/") + "/" + filename.lstrip("/"), 'wb')
ftp.retrbinary('RETR %s' % filename, handle.write)

A = filename

ftp = ftplib.FTP("IP")
ftp.login("USR Name", "Pass")
ftp.cwd("/Dir")


try:
    ftp.retrbinary("RETR " + filename ,open(A, 'wb').write)
except:
    print "Error"

FILENAME = 'StarWars.avi'    

with ftplib.FTP(FTP_IP, FTP_LOGIN, FTP_PASSWD) as ftp:
    ftp.cwd('movies')
    with open(FILENAME, 'wb') as f:
        ftp.retrbinary('RETR ' + FILENAME, f.write)

Of course it would we be wise to handle possible errors.
