Overview:

  • The login() method of FTP class, initiates a logged-in session with the FTP server for a user.
  • The login() method sends the user credentials to the FTP server. Once the FTP server completes the user authentication, it creates an FTP session.
  • The login() function roughly translates into issuing of FTP commands: USER and PASS.
  • For the login() to work, the connection to the FTP server should have been already established either through the constructor - FTP() or through the method connect().

 

Example:

# Example Python program that logs in as an anonymous user

from ftplib import FTP

 

# Create an FTP object

ftpObject = FTP();

 

# Connect to the FTP server

connectResponse = ftpObject.connect(host="someserverthatallowstesting");

print(connectResponse);

 

# Login to the FTP server

loginResponse = ftpObject.login();

print(loginResponse);
