Python - SFTP connection, upload file and delete a file from SFTP server

 Below is the python program which will connect to SFTP server, upload a file to SFTP server and delete a specific file from SFTP server. Here is the code:

import paramiko

from paramiko.ssh_exception import SSHException

import os

import time

hostname = 'hostname here'

username = 'username here'

password = 'password here'

port = PORT_NO

SSH_Client = paramiko.SSHClient()

SSH_Client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

SSH_Client.connect(hostname=hostname,

                   port=port,

                   username=username,

                   password=password,

                   look_for_keys=False)

sftp_client = SSH_Client.open_sftp()

print("Connection successfully established ... ")

remoteFilePath = "/home"

# Output: lists of files ['my-directory', 'my-file']

print(f"lists of files {sftp_client.listdir(remoteFilePath)}")

# Output: lists of files [<SFTPAttributes: [ size=0 mode=0o40755 atime=0 mtime=0 ]>, <SFTPAttributes: [ size=50615986 mode=0o100644 atime=1701012997 mtime=1701012997 ]>]

print(f"lists of files {sftp_client.listdir_attr(remoteFilePath)}")

file_to_delete = "file path of SFTP folder"

upload_file_name = 'SFTP_Test.txt'

localFilePath = "local path"+upload_file_name

remoteFilePath = "remote path"

try:

  sftp_client.put(localFilePath, remoteFilePath+'/SFTP_Test.txt')

  print(f"{file_to_delete} => File is successfully placed on SFTP server ... ")

  print("Wait time begin is : ", time.ctime())

  time.sleep(15)

  print("Wait time end is : ", time.ctime())

  # Remove file

  sftp_client.remove(file_to_delete)

  print(f"{file_to_delete} => file is successfully deleted from SFTP server ... ")

except FileNotFoundError as err:

  print(f"File {localFilePath} was not found on the local system")

except ConnectionResetError as cre:

    print(f"Connection Reset Error")

except SSHException as cre:

    print(f"SSHException")

finally:

    sftp_client.close()
