download - Python FTPLIB error 530 Permission Denied -

i've tried script below:

import os ftplib import ftp  ftp = ftp("ftpsite","myuser", "mypass") ftp.login() ftp.retrlines("list")  ftp.cwd("folderone") ftp.cwd("subfolder")  listing = [] ftp.retrlines("list", listing.append) words = listing[0].split(none, 8) filename = words[-1].lstrip()  #download file local_filename = os.path.join(r"c:\example", file) lf = open(local_filename, "wb") ftp.retrbinary("retr " + filename, lf.write, 8*1024) lf.close() 

but everytime run script, says:

traceback (most recent call last):   file "c:\user\desktop\sample\ex.py", line 4, in <module>     ftp = ftp("ftpsite", "myuser", "mypass")   file "c:\python27\lib\ftplib.py", line 119, in __init__     self.login(user, passwd, acct)   file "c:\python27\lib\ftplib.py", line 387, in login     resp = self.sendcmd('user ' + user)   file "c:\python27\lib\ftplib.py", line 244, in sendcmd     return self.getresp()   file "c:\python27\lib\ftplib.py", line 219, in getresp     raise error_perm, resp error_perm: 530 permission denied. 

i don't know 530 permission denied means.can tell me means?

• it seems ftp server allows anonymous access; don't need pass username, password.
• ftp constructor accept hostname(or ip), not url.
