Is there a Python caching library?

I'm looking for a Python caching library but can't find anything so far. I need a simple dict-like interface where I can set keys and their expiration and get them back cached. Sort of something like:

cache.get(myfunction, duration=300)

which will give me the item from the cache if it exists or call the function and store it if it doesn't or has expired. Does anyone know something like this?

This project aims to provide "Caching for humans" (seems like it's fairly unknown though)

Some info from the project page:

Installation

pip install cache

Usage:

import pylibmc
from cache import Cache

backend = pylibmc.Client(["127.0.0.1"])

cache = Cache(backend)

@cache("mykey")
def some_expensive_method():
    sleep(10)
    return 42

# writes 42 to the cache
some_expensive_method()

# reads 42 from the cache
some_expensive_method()

# re-calculates and writes 42 to the cache
some_expensive_method.refresh()

# get the cached value or throw an error
# (unless default= was passed to @cache(...))
some_expensive_method.cached()
