Getting started:

import time

from ttlstore import TTLStore


d = TTLStore(ttl=1) # use d like a python dictionary
d['a'] = 'b'
time.sleep(2)
# 'a' is not present any more in the memory
print(d)

def call_me(key, value):
   print(key, value)

d = TTLStore(ttl=1, callback=call_me)
d['a'] = 'b'
time.sleep(2)
# 'a' is not present any more in the memory and call_me is called.
print(d)
