[Closed] Merge Bones

Does anyone have a sample script oh how i would merge 2 bones and transfer any weights the one bone had to the other?
For example i have a rigged character that has a bone on their hand called weapon1 and now i have a weighted gun that is a separate model in the scene with a bone called main weapon I want to take that main weapon bone and delete it while transferring any weights it had to the bone weapon1. Thanks so much for any help in advance
