Run a Python script on SSH

Hello, I will need a python script that does next task: I an using many VPS servers and I will need a python script to change between IP`s for my domains. For the Dynamic DNS I am ussing dynu.com. They have an API command that you can change the IPV4 for all domains from my account: [login to view URL] So my script will be easy. I will have a txt file with all my VPS servers IP`s from where the script will take ip`s. The script will check everytime if the actual IP is working, we will have 3 checks at 30 seconds(sometime the servers get down because of huge load) , if still after this 3 checks the IP is not working, we will run the script with next IP from the txt file: [login to view URL] and so on if also this one will go down. I will need also to recieve a notice on mail if an IP will go down, and the next one is changing. Thanks
