pymongo 3.2.2

Python driver for MongoDB <>


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.

How To Ask For Help

Please include all of the following information when opening an issue:

  • Detailed steps to reproduce the problem, including full traceback, if possible.

  • The exact python version used, with patch level:

    $ python -c "import sys; print(sys.version)"
  • The exact version of PyMongo used, with patch level:

    $ python -c "import pymongo; print(pymongo.version); print(pymongo.has_c())"
  • The operating system and version (e.g. Windows 7, OSX 10.8, …)

  • Web framework or asynchronous network library used, if any, with version (e.g. Django 1.7, mod_wsgi 4.3.0, gevent 1.0.1, Tornado 4.0.2, …)

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.

Do not install the “bson” package. PyMongo comes with its own bson package; doing “easy_install bson” installs a third-party package that is incompatible with PyMongo.


The PyMongo distribution is supported and tested on Python 2.x (where x >= 6) and Python 3.x (where x >= 2). PyMongo versions before 3.0 also support Python 2.4, 2.5, and 3.1.

Optional packages:

  • backports.pbkdf2, improves authentication performance with SCRAM-SHA-1, the default authentication mechanism for MongoDB 3.0+. It especially improves performance on Python older than 2.7.8, or on Python 3 before Python 3.4.
  • pykerberos is required for the GSSAPI authentication mechanism.
  • monotonic adds support for a monotonic clock, which improves reliability in environments where clock adjustments are frequent. Not needed in Python 3.3+.
  • wincertstore adds support for verifying server SSL certificates using Windows provided CA certificates on older versions of python. Not needed or used with versions of Python 2 beginning with 2.7.9, or versions of Python 3 beginning with 3.4.0.
  • certifi adds support for using the Mozilla CA bundle with SSL to verify server certificates. Not needed or used with versions of Python 2 beginning with 2.7.9 on any OS, versions of Python 3 beginning with Python 3.4.0 on Windows, or versions of Python 3 beginning with Python 3.2.0 on operating systems other than Windows.

Additional dependencies are:

  • (to generate documentation) sphinx
  • (to run the tests under Python 2.6) unittest2


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')
>>> db.my_collection.insert_one({"x": 10}).inserted_id
>>> db.my_collection.insert_one({"x": 8}).inserted_id
>>> db.my_collection.insert_one({"x": 11}).inserted_id
>>> 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 run python test in the root of the distribution. Note that you will need unittest2 to run the tests under Python 2.6.

To verify that PyMongo works with Gevent’s monkey-patching:

$ python gevent

Or with Eventlet’s:

$ python eventlet
