About

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.

PyMongo supports MongoDB 3.6, 4.0, 4.2, 4.4, and 5.0.

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 Community Forums.

Bugs / Feature Requests

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

• Create an account and login.

• Navigate to the PYTHON project.

• Click Create Issue - Please provide as much information as possible about the issue type and how to reproduce it.

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

Installation

PyMongo can be installed with pip:

$ python -m pip install pymongo

Or easy_install from setuptools:

$ python -m easy_install pymongo

You can also download the project source and do:

$ python setup.py install

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

Dependencies

PyMongo supports CPython 3.7+ and PyPy3.7+.

Optional dependencies:

GSSAPI authentication requires pykerberos on Unix or WinKerberos on Windows. The correct dependency can be installed automatically along with PyMongo:

$ python -m pip install "pymongo[gssapi]"

MONGODB-AWS authentication requires pymongo-auth-aws:

$ python -m pip install "pymongo[aws]"

Support for mongodb+srv:// URIs requires dnspython:

$ python -m pip install "pymongo[srv]"

OCSP (Online Certificate Status Protocol) requires PyOpenSSL, requests, service_identity and may require certifi:

$ python -m pip install "pymongo[ocsp]"

Wire protocol compression with snappy requires python-snappy:

$ python -m pip install "pymongo[snappy]"

Wire protocol compression with zstandard requires zstandard:

$ python -m pip install "pymongo[zstd]"

Client-Side Field Level Encryption requires pymongocrypt:

$ python -m pip install "pymongo[encryption]"

You can install all dependencies automatically with the following command:

$ python -m pip install "pymongo[gssapi,aws,ocsp,snappy,srv,tls,zstd,encryption]"

Additional dependencies are:

• (to generate documentation) sphinx

Examples

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.name
'test'
>>> db.my_collection
Collection(Database(MongoClient('localhost', 27017), 'test'), 'my_collection')
>>> db.my_collection.insert_one({"x": 10}).inserted_id
ObjectId('4aba15ebe23f6b53b0000000')
>>> db.my_collection.insert_one({"x": 8}).inserted_id
ObjectId('4aba160ee23f6b543e000000')
>>> db.my_collection.insert_one({"x": 11}).inserted_id
ObjectId('4aba160ee23f6b543e000002')
>>> db.my_collection.find_one()
{'x': 10, '_id': ObjectId('4aba15ebe23f6b53b0000000')}
>>> for item in db.my_collection.find():
...     print(item["x"])
...
10
8
11
>>> db.my_collection.create_index("x")
'x_1'
>>> for item in db.my_collection.find().sort("x", pymongo.ASCENDING):
...     print(item["x"])
...
8
10
11
>>> [item["x"] for item in db.my_collection.find().limit(2).skip(1)]
[8, 11]

Documentation

Documentation is available at pymongo.readthedocs.io.

To build the documentation, you will need to install sphinx. Documentation can be generated by running python setup.py doc. Generated documentation can be found in the doc/build/html/ directory.

Testing

The easiest way to run the tests is to run python setup.py test in the root of the distribution.

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

$ python green_framework_test.py gevent

Or with Eventlet’s:

$ python green_framework_test.py eventlet
