ttldict2

Another dictionary with expiring keys.

Details

There are quire a few expiring/ttl dictionary libraries available. This one might be a better choice for you if:

• Only need support for Python 3.7+ or PyPy3
• Use it in a single/asyncio thread
• Work correctly regardless of system-clock adjustments

The implementation is a wrapper around the builtin dict. As a design choice the methods that are not wrapped with TTL logic are accessible and can be used with caution.

Install & usage

It is available on PyPI:

$ python -m pip install ttldict2

>>> import time
>>> import ttldict2
>>> d = ttldict2.TTLDict(ttl_seconds=1.0)
>>> d["a"] = 5
>>> d.get("a")
5
>>> time.sleep(1.1)
>>> d.get("a")
None
