What is ftplib module?
This module defines the class FTP and a few related items. The FTP class implements the client-side of the FTP protocol. You can use this to write Python programs that perform a variety of automated FTP jobs, such as mirroring other FTP servers.
We will use a test FTP server, it is called DLPTEST and we are going to use the below text file for all operations:
Let’s Understand step by step implementation:
- Enter Required Information, the information will be available click here.
Python3
# Import Moduleimport ftplib# Fill Required InformationHOSTNAME = "ftp.dlptest.com"USERNAME = "dlpuser@dlptest.com"PASSWORD = "eUj8GeW55SvYaswqUyDSm5v6N" |
Note: Password will change time to time, make sure you visit their website for the correct credentials.
- Connect to Server
Python3
# Connect FTP Serverftp_server = ftplib.FTP(HOSTNAME, USERNAME, PASSWORD)# force UTF-8 encodingftp_server.encoding = "utf-8" |
- Upload the File (To upload a file, we will use storbinary() method)
Syntax:
# Store a file in binary transfer mode storbinary(command, **)
Python3
# Enter File Name with Extensionfilename = "gfg.txt"# Read file in binary modewith open(filename, "rb") as file: # Command for Uploading the file "STOR filename" ftp_server.storbinary(f"STOR {filename}", file) |
- Get the list of directories using dir() method. The test server will remove files after 30 minutes.
Python3
# Get list of filesftp_server.dir() |
Output:
- Download the File (To download a file, we will use retrbinary() method.
Python3
# Enter File Name with Extensionfilename = "gfg.txt"# Write file in binary modewith open(filename, "wb") as file: # Command for Downloading the file "RETR filename" ftp_server.retrbinary(f"RETR {filename}", file.write) |
- Close the FTP Connection.
Python3
# Display the content of downloaded filefile= open(filename, "r")print('File Content:', file.read())# Close the Connectionftp_server.quit() |
Output:
Below is the complete program for uploading the file in FTP Server:
Python3
# Import Moduleimport ftplib# Fill Required InformationHOSTNAME = "ftp.dlptest.com"USERNAME = "dlpuser@dlptest.com"PASSWORD = "eUj8GeW55SvYaswqUyDSm5v6N"# Connect FTP Serverftp_server = ftplib.FTP(HOSTNAME, USERNAME, PASSWORD)# force UTF-8 encodingftp_server.encoding = "utf-8"# Enter File Name with Extensionfilename = "File Name"# Read file in binary modewith open(filename, "rb") as file: # Command for Uploading the file "STOR filename" ftp_server.storbinary(f"STOR {filename}", file)# Get list of filesftp_server.dir()# Close the Connectionftp_server.quit() |
Output:
Below is the complete program for downloading the file in FTP Server:
Python3
# Import Moduleimport ftplib# Fill Required InformationHOSTNAME = "ftp.dlptest.com"USERNAME = "dlpuser@dlptest.com"PASSWORD = "eUj8GeW55SvYaswqUyDSm5v6N"# Connect FTP Serverftp_server = ftplib.FTP(HOSTNAME, USERNAME, PASSWORD)# force UTF-8 encodingftp_server.encoding = "utf-8"# Enter File Name with Extensionfilename = "gfg.txt"# Write file in binary modewith open(filename, "wb") as file: # Command for Downloading the file "RETR filename" ftp_server.retrbinary(f"RETR {filename}", file.write)# Get list of filesftp_server.dir()# Display the content of downloaded filefile= open(filename, "r")print('File Content:', file.read())# Close the Connectionftp_server.quit() |
Output:
