Earlier quoted context omitted.
Once you bag a snake, they're pretty easy to move around. Getting them into a sack isn't as hard as you might imagine either. Obviously, it's going to be more difficult for a larger snake, but it's way easier than getting, say, a cat into a cat carrier.
I know nothing about snake hunting other than the 3 youtube videos I just watched ( https://www.youtube.com/shorts/5JB_bzQwtZ8 ), but this professional sure makes getting them into the sack is about as hard and dangerous as I would imagine. Seems like you're one slip up from getting a chunk of your body removed (like that dude in the youtube video's arm).
Most of the pythons they are bagging are much smaller than that, and YouTubers have an incentive to make bagging a snake look more thrilling than it usually is.
