How can I replace a string value with its corresponding Boolean value in a nested dictionary in Python?

I was recently given a project to do for my Python college course. Basically, you save a dictionary in a csv file with csv.DictWriter, and then you load it back into another dictionary with csv.DictReader.

The file names of the images correspond to the rows in the column ‘imdbId’ in the df, with the addition that they have the .jpg suffix. I would like to drop all rows in my

When should I use None vs False?
