Chilkat2 Python Downloads install with pip pip3 install chilkat2 or download... Python Module for Windows, Linux, Alpine Linux, MacOS, Solaris

import sys

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

sftp = chilkat2.SFtp()

# Set some timeouts, in milliseconds:
sftp.ConnectTimeoutMs = 5000
sftp.IdleTimeoutMs = 10000

# Connect to the SSH server.  
# The standard SSH port = 22
# The hostname may be a hostname or IP address.
hostname = "sftp.example.com"
port = 22
success = sftp.Connect(hostname,port)
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# Authenticate with the SSH server.  Chilkat SFTP supports
# both password-based authenication as well as public-key
# authentication.  This example uses password authenication.
success = sftp.AuthenticatePw("myLogin","myPassword")
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# After authenticating, the SFTP subsystem must be initialized:
success = sftp.InitializeSftp()
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

# Download the file:

localFilePath = "c:/temp/hamlet.xml"
remoteFilePath = "subdir1/subdir2/hamlet.xml"
# The ResumeDownloadFileByName method will check
# the local file and begin downloading the remote file
# at the appropriate point.  For example, if the local
# file is already 215624 bytes long, it will begin downloading
# the remote file at the 215625'th byte -- appending to
# the local file.
success = sftp.ResumeDownloadFileByName(remoteFilePath,localFilePath)
if (success != True):
    print(sftp.LastErrorText)
    sys.exit()

print("Success.")
