from ftplib import FTP

ftp = FTP('ftp.example.com')
ftp.login(user='username', passwd='password')
ftp.cwd('/path/to')
filename = 'file.txt'
with open(filename, 'wb') as f:
    ftp.retrbinary('RETR ' + filename, f.write)
ftp.quit()

import paramiko

hostname = 'example.com'
port = 22
username = 'username'
password = 'password'
remote_path = '/path/to/file.txt'
local_path = 'file.txt'

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, port, username, password)
sftp = ssh.open_sftp()
sftp.get(remote_path, local_path)
sftp.close()
ssh.close()
