Today the humidity in Jakarta is quite high, but I've managed to complete my review of the Python exception handling module as planned. During the afternoon office hours, I noticed the sky outside gradually darkening, as if a midday thunderstorm is on its way. This reminds me of the chapter on data persistence in the syllabus—just as rain changes the state of the ground, the way data is stored can affect program stability. I plan to emphasize this point in the next class. Right now, I'm taking a short break to enjoy a slice of buttered bread to recharge, and I'll continue preparing next week's lesson plan. Staying focused and efficient.
