I was reading up on Monads because of the reactive course. [0] I translated the code in "Monads for functional programming" (the linked paper) to Python a few weeks back – [1]

Not sure if it will actually help anyone, but it did help me in realising that I had not understood some code, but had instead just glossed over it. The State Monad, for example. [2]
