supycache 介绍
supycache 是 Python 对缓存的简单封装库，支持包括内存缓存、memcached 和 redis。
示例代码：
import time
import supycache
@supycache.supycache(cache_key='result')
def execute_expensive():
time.sleep(15)
return 42
print execute_expensive() # This will take 15 seconds to execute ...
42
print execute_expensive() # ...not this tho', because the value is cached ...
42
print supycache.default_backend.get('result') # ..keyed as `result`
42
