如何让 python 脚本 (abc.py) 在连接丢失或 SSH 连接终止后继续在 AWS 上执行？

Question

I was using Jupyter notebook on AWS AMI and using the port forwarding on Windows using PuTTY . I got my connection terminated and all the work of 24 hours is lost now and I'm unable to get that. So I used a script instead of Notebook and the same thing happened. I used to think that the process would keep going on even if the Shell connection is lost. But next time I login, I don't see anything. I used top , htop aux to find if my processes are still running but they don't show my process. Please help how can I stop this from happening.

I am using Windows on 10 with Putty on local and Ubuntu 18 on the AWS AMI.
