python缓存笔记[总结]

1. python处理memcache示例

import memcache
def test(key, value):
    """
     >>> test("foo", "bar")
     'bar'
      >>> test("hello", 123)
      123
    """
    mc = memcache.Client(['127.0.0.1:11211'], debug=0)
    mc.set(key, value, time=5)
    mc.add(key, value, time=5)
    value = mc.get(key)
    return value

def test2(dict={}, key_prefix=""):
    """
     >>> test2({'k1':1, 'k2':2}, key_prefix='pfx_')
     {'k2': 2, 'k1': 1}
    """

    mc = memcache.Client(['127.0.0.1:11211'], debug=0)
    mc.set_multi(dict, key_prefix=key_prefix)
    return mc.get_multi(['k1', 'k2', 'nonexist'], key_prefix=key_prefix)
