[docs] [issue18840] Tutorial recommends pickle module without any warning of insecurity

[Antoine Pitrou]

Antoine Pitrou added the comment:

I would be ok with changing that part of the tutorial to use json. Since json is much better known outside of the Python programming circles, and since its output is human-readable, it's probably a better fit for the tutorial. pickle can be mentioned as a more powerful and more dangerous alternative.
