Unfortunately I am not good at cutting and pasting articles. But if you google “giant python Indonesia” you will come across the story of a 49 foot 983 pound python in captivity in Indonesia. You can also see images of this giant snake as well as a videotape.
I looked that up. In that case i’d switch to a 12 gauge automatic with the plug taken out, use deer slugs and make sure I brought along a fried similarly armed.
