So I know the .append function adds elements to a list. But that only works as long as the script is running. If I rerun the file, the list is back to its previous state with no changes made. Is there a way to save the changes?

    You could write it to a file and then read it. File I/O is a standard way to maintain state between runs. – John Coleman Aug 05 '21 at 11:16

    Either save it to a database or a text file, or change the python code as you run it –  Aug 05 '21 at 11:17

You can save the list to a file after everything is done:

Here for a+ mode: All file handling modes <---Here

a+: Open for reading and appending (writing at end of file). The file is created if it does not exist.

with open('test_file','a+') as file:
   lst=[...]
   ....
   file.write(lst)
