To my surprise, my son¹ asked me to teach him how to use JSON in Python today. His grandfather showed him JSON files from his website earlier today, and now my son is mad for reading and writing JSON himself.

We graduated from Turtle graphics to data structures and file I/O. I introduced to him Python dictionary and the list, showed him how to converted both to JSON, and then showed him how to write the JSON to a file. In Python, it is very easy.

My wife is looking for computer science courses for him now.
