You can create an SSH tunnel through multiple hosts in Python using the Paramiko library. Here’s an example of how to do it:

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# Connect to first host
ssh.connect('first_host', username='username', password='password')

# Connect to second host via first host
transport = ssh.get_transport()
dest_addr = ('second_host', 22)
local_addr = ('localhost', 10022)
channel = transport.open_channel("direct-tcpip", dest_addr, local_addr)

# Connect to third host via second host
ssh2 = paramiko.SSHClient()
ssh2.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh2.connect('localhost', username='username', password='password', sock=channel)

# Execute command on third host
stdin, stdout, stderr = ssh2.exec_command('ls -l')
print(stdout.read().decode())
This code connects to the first host using SSH, then connects to the second host via the first host using a direct-tcpip channel, and finally connects to the third host via the second host using SSH again.

I hope this helps! Let me know if you have any other questions.
