Python: get list of memcached key values by wildcards

I am using memcached with pylibmc as binaries in my Django app. Now what I want to get list of key values from cache.

Suppose I have this key value pair data in cache,

{'Key_1':[1,2,3]} {'Key_2':[4,5,6]} {'Key_3':[6,7,8]}

I can get a single record by 

cache.get('Key_1')

I want to get all Key_*data

cache.get('Key_*')

Anyone suggest a way? or is it possible?

Thanks!

You could either use the mcdict library and iterate through memcached like a normal dictionary or else you could look at the mcdict source code and apply the same technique in your own code.

If you have dictionary than you can do something like this:

import re
dict = { 'Key_1':[1,2,3], 'Key_2':[4,5,6], 'Key_3':[6,7,8] }
r = re.compile(r"Key_\d+")   // matching expression
matching_keys = filter(r.match, dict.keys())

This way you can get all matching keys and then simply iterate on those keys.
