I am teaching a course on Udemy about Python GUI Programming

First time HN user here, I lurked it for some time and I quite like it.

Anyway, the course is a paid course, however I present to you a coupon - just enter HN and the price will be down to $10.

I'd also appreciate any feedback you could give me.

Additionally, if this is completely inappropriate (for me to post here), please let me know!
