(upbeat techno music) - [Instructor] For this solution, I chose to save the canvas and scribe objects as JSON files. This is the natural choice because we have a combination of dictionaries and lists going on here, and frankly, it's just the easiest. All you need is json.dumps and it just dumps the output of the toDict method to that JSON file. On the flip side, we need the from file method.

I also surrounded the fromDict method with this tricep block because really anything could go wrong here. The file could be missing, not readable, not actual JSON. Even if there is JSON, there might have been a problem with how it was created. I mean, who knows. So…
