# Using our JSON service from Python with key / value cache
# Here's one for you to try ...
# http://api.geonames.org/citiesJSON?north=51.3&south=51.4&east=-2.1&west=-2.2&lang=en&username=[ask graham]
# Get an object from a service if we don't have a recent local copy
localstore = kvcache.kvcache("http://www.wellho.net/services/*.json")
stuff = localstore.get("pix")
source = localstore.latest_source
# We now have it as a serialised stream - in JSON format.
# turn it into an object (type dict)
memory = json.loads(stuff)
# A top level look (so the trainee can see what's happening!)
print " ---- Here is what we have ---- "
for itemname in memory.keys():
print "For your training info, the data is",source
print " ------------------------------- "
# or in more detail

print "This was generated at",memory["timedat"],time.strftime("%c",toby)
print "Searching only for",memory["lookfor"]
print "All available records requested"
# And look at the detailed stuff within the response too!
for record in memory["acc"]:
print record["when"], record["which"]
