How to Pick-up/Drag/Throw Rigidbodies? [3D]

I'm looking for pick-up/carry/drag/throw mechanics like those in "Amnesia: The Dark Descent". I've tried many other options that involve coding but I must have been missing something because they all cause errors and prevent me from playing the game. I'm new to Unity and don't know coding in Java or C# (I know mostly Python). I really need some help with this, preferably specific instructions.

Also, this game takes place while the player is in 1st person AND (most importantly) not able to move, so the distance to pick things up has to be able to vary, or at least be pretty long.

ALSO, my first person camera is the FirstPersonController prefab instead of the Main Camera, which may be the problem as to why the scripts aren't working.

Thanks in advance!
