Will interrupting the script delete the progress in Jupyter Notebook?

Question

I'm currently running a script in Jupyter Notebook which loops over a Dataframe and manipulates the data of the current row. As my Dataframe has thousands of rows and each loop takes a while to run, I am wondering whether it's safe to interrupt the script without losing all of my progress?

I am keeping track of rows that have already been processed so I could just start where I left off in the case that the manipulations on the Dataframe don't get lost. I don't want to take the risk of trying it out right now so advice would be appreciated.

Unless you are storing progress in external files, interrupting Jupyter will lose you data. I highly do not recommend on counting on the variables inside of Jupyter on being in some state if you are mid-way through a calculation, just save intermediate steps in files to track progress, chunking as you go.
