None of those numbers sound all that high to me. It's a catch-22: if you rarely use swap, you don't have a problem, but you probably don't need swap space to begin with. However, if you want to lean on swap space heavily and create a Python program that operates on 100 GB of memory, garbage collections are going to create quite a rewrite load on the disk.
