Actually it's not too hard. You can construct the json query syntax 
fairly easily from python once you understand it:

>>> import json

>>> query = json.dumps( { "$and":[ { "$gt": {"age": 5} }, { "$not": 
{"name": "curly"} } ] } )

>>> query

'{"$and": [{"$gt": {"age": 5}}, {"$not": {"name": "curly"}}]}'
