Python driver for MongoDB <>

Project description


See the mongo site for more information. See github for the latest source.


Mike Dirolf <>


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


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 has been tested on Python 2.x, where x >= 3. On Python 2.3 the optional C extension will not be built. This will negatively affect performance, but everything should still work.

Additional dependencies are:

  • ElementTree (this is included with Python >= 2.5)

  • (to generate documentation) epydoc

  • (to auto-discover tests) nose


Here’s a basic example (for more see the examples/ directory):

>>> from pymongo.connection import Connection
>>> connection = Connection("localhost", 27017)
>>> db = connection.test
>>> db.my_collection
Collection(Database(Connection('localhost', 27017), u'test'), u'my_collection')
>>>{"x": 10})
>>>{"x": 8})
>>>{"x": 11})
>>> db.my_collection.find_one()
{u'x': 10, u'_id': ObjectId('D\x87\xdd\xe8\xd6\x0f\x89\xfc\xab\x06\xac\x8e')}
>>> for item in db.my_collection.find():
...     print item["x"]
>>> from pymongo import ASCENDING
>>> db.my_collection.create_index("x", ASCENDING)
>>> for item in db.my_collection.find().sort("x", ASCENDING):
...     print item["x"]
>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
[8, 11]


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