I’m currently on screen no. 3 (“Deleting Wrong Data”) in the mobile app guided project. I have found the row in question and have deleted it. As I’m working on my local Jupyter, when I want to stop working on the project, I’ll halt and close the notebook.
As you said you would do halt and close previous session then, it is fine to re-run del data(index) unless you are saving it to memory or back to actual file. But do not run this twice in same session else you would get error or delete wrong data.
I don’t have any another idea in mind right now but same time I don’t see any problem with this.
