PyJudy might be what you're looking for, though I've never used it:

"Judy's key benefits are scalability, high performance, and memory
efficiency. A Judy array is extensible and can scale up to a very large
number of elements, bounded only by machine memory." ... "PyJudy arrays
are similar to Python dictionaries and sets."
