Sometimes it's great to have your scripts running while you sleep. While doing so, it's important to ensure it doesn't put too much load on your droplet. Otherwise any website you may be hosting on your droplet may crash.

To enable continuous scripts, first you need to copy and paste your code to a directory on your droplet. For example you can use Filezilla or another FTP application, to upload your file. Alternatively you can pull/clone it with GIT. You may put it in a new directory under the '/' folder. Then SSH into your server using Putty (for Windows) or a similar program

Then type the following code nohup python3 yourscript.py & This will create a nohup.out file in the same folder. The '&' at the end sends the process to the background, and frees up your terminal.

Later to stop the process you need to find the process ID (PID) of the python3 process you set running. While SSHing into your server you can type the following to get a list of all the processes running and their ID

    ps -a
    ps -A (will show Python processes aswell)
    kill 7196 (to kill the process)

If there are multiple Python3 processes I am not sure how you can identify them. This may be an interesting thing to test out.
