Parsing JSON string/object in Python

I've recently started working with JSON in python. Now I'm passing a JSON string to Python(Django) through a post request. Now I want to parse/iterate of that data. But I can't find a elegant way to parse this data, which somehow I'm pretty sure exists.

data = request.POST['postformdata']
print data
{"c1r1":"{\"Choice\":\"i1\"}","c2r1":"{\"Bool\":\"i2\"}","c1r2":"{\"Chars\":\"i3\"}"}

jdata = json.loads(data)
print jdata
{u'c1r2': u'{"Chars":"i3"}', u'c1r1': u'{"Choice":"i1"}', u'c2r1': u'{"Bool":"i2"}'}

This is what was expected. But now when I want to get the values, I start running into problems. I have to do something like 

mydecoder = json.JSONDecoder()
for part in mydecoder.decode(data):                                             
    print part
# c1r2 c1r1 c2r1 ,//Was expecting values as well

I was hoping to get the value + key, instead of just the key. Now, I have to use the keys to get values using something like

print jdata[key]

How do I iterate over this data in a simpler fashion, so that I can iterate over key, values?

Just for others to help. In Python3 dict.iteritems() has been renamed to dict.iter()

To iterate key and value, you can write

for key, value in jdata.iteritems():
    print key, value

You can read the document here: dict.iteritems
