When trying to use $inc I get a Syntax error stating that $set is wrong. My query is as follow:
mongo_db.campaign.update({'_id': str(campaign_id)}, { $inc: { 'item': 1 } }):
I've looked at the mongo documentation (http://docs.mongodb.org/manual/reference/operator/inc/) and other examples on SO but I can't find what's wrong. Any suggestions?
Thanks!

PyMongo is thread-safe and even provides built-in connection pooling for threaded applications.
There's no need to close a Connection instance, it will clean up after itself when Python garbage collects it. You should use MongoClient instead of Connection ; Connection is deprecated. To take advantage of connection pooling, you could create one MongoClient that lasts for the entire life of your process.
MongoDB must be installed on the machine or server that is being used to run Python scripts.
$inc isn't a valid Python identifier. You should pass it as a string, like everything else:
mongo_db.campaign.update({'_id': str(campaign_id)}, {'$inc': {'item': 1}})
The MongoDB docs you linked are the general MongoDB documentation, not PyMongo-specific; you can't copy/paste them literally and expect things to work.
