How to run Screen command on EC2 instance from Python script

Question

I have tried launching a EC2 instance from pycharm using a Python script. As part of the launch process, I have downloaded a .sh script from s3 and have executed below commands.

commands = [
    "aws s3 cp s3://sample/test.sh /home/ubuntu/test.sh",
    "chmod +x /home/ubuntu/test.sh",
    "sudo apt-get update",
    "./test.sh"
]

However, when the last command './test.sh' is executed, I want to get out of the flow and create few more instances. But, as the script ./test.sh is a long running script, its not exiting the loop. I would like to submit the job as a background Screen job, but, was not able to open a screen using python code snippets. I am using paramiko module to connect to EC2 instance.

Are you downloading and executing the script on your local machine? Also, could you provide the snippet of code that failed to open a screen session for you? — Michael Ababio

I have downloaded the script in EC2 instance. I changed the ./test.sh to "screen -d -m ./test.sh" and it worked. — ZZzzZZzz

I have changed the above statement from ./test.sh to screen -d -m ./test.sh and it did the trick for me.
