comment Show that the equation solves the Black-Scholes PDE
You're getting downvoted because after receiving good help you just ask for more instead of showing any work yourself. Your question looks like homework and our users are generally encouraged to solve that themselves as much as possible. For the sake of the people that answer but also for their own: you learn most by doing.

comment Black-Scholes model
I believe there is some value in a nice worked example (with code, nice little tables and graphs, etc. a bit textbook like) on what happens when hedging is not continuous. Maybe not exactly on-topic but a nice to have for people that have just started. However, this just looks like homework and that I don't like.
