Example of TTLCache from cachetools

ttl_cache_example.py

from cachetools import TTLCache
from sched import scheduler

cache = TTLCache(maxsize=128, ttl=5)

runner = scheduler()

cache["abc"] = 42

def display_cached_value(cache_key):
    try:
        cached_value = cache[cache_key]
        print("{0}={1}".format(cache_key, cached_value))
    except KeyError:
        print("{0}=Not in cache".format(cache_key))

runner.enter(2, 1, display_cached_value, argument=("abc",))
runner.enter(6, 1, display_cached_value, argument=("abc",))
runner.run()
