Discussion on: Cache Me Outside: Speed Boosts in Python

Yeah, it seems like it. It doesn't look like there is an easy way to do that with the standard library @lru_cache, but you could definitely do it if you rolled your own. I guess the other option if you were going to have it run for a long time (like for a web-app or something) would be to provide a preload function that just exercises those inputs artificially:

def preload(func, inputs):
    """Runs the function with the provided list of inputs,
    filling in the cache before expected client use"""
    for input in inputs:
        func(input)

I'm working on another post about decorators, so I'll work a preloaded memoization example into it :)
