PyMongo - the Python driver for MongoDB

This branch is 53 commits behind mongodb:master

Fix tox compatibility.

The tox testing tool has dropped support for python 2.5
(and therefore jython) and by default sets PYTHONHASHSEED
to a random value. pip is dropping python 3.1 in its next
release so we might as well drop that from tox.ini now as

The PyMongo distribution contains tools for interacting with MongoDB database from Python. The bson package is an implementation of the BSON format for Python. The pymongo package is a native Python driver for MongoDB. The gridfs package is a gridfs implementation on top of pymongo.

Support / Feedback

For issues with, questions about, or feedback for PyMongo, please look into our support channels. Please do not email any of the PyMongo developers directly with issues or questions - you're more likely to get an answer on the mongodb-user list on Google Groups.

Bugs / Feature Requests

Think you’ve found a bug? Want to see a new feature in PyMongo? Please open a case in our issue management tool, JIRA:

Bug reports in JIRA for all driver projects (i.e. PYTHON, CSHARP, JAVA) and the Core Server (i.e. SERVER) project are public.

Security Vulnerabilities

If you’ve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here.


If you have setuptools installed you should be able to do easy_install pymongo to install PyMongo. Otherwise you can download the project source and do python install to install.


The PyMongo distribution is supported and tested on Python 2.x (where x >= 4) and Python 3.x (where x >= 1). PyMongo versions <= 1.3 also supported Python 2.3, but that is no longer supported.

Additional dependencies are:

  • (to generate documentation) sphinx
  • (to auto-discover tests) nose


Here's a basic example (for more see the examples section of the docs):

>>> import pymongo
>>> client = pymongo.MongoClient("localhost", 27017)
>>> db = client.test
>>> db.my_collection
Collection(Database(MongoClient('localhost', 27017), u'test'), u'my_collection')
>>>{"x": 10})
>>>{"x": 8})
>>>{"x": 11})
>>> db.my_collection.find_one()
{u'x': 10, u'_id': ObjectId('4aba15ebe23f6b53b0000000')}
>>> for item in db.my_collection.find():
...     print item["x"]
>>> db.my_collection.create_index("x")
>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
...     print item["x"]
>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
[8, 11]


You will need sphinx installed to generate the documentation. Documentation can be generated by running python doc. Generated documentation can be found in the doc/build/html/ directory.


The easiest way to run the tests is to install nose (easy_install nose) and run nosetests or python test in the root of the distribution. Tests are located in the test/ directory.
