PyMongo

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 4.0, 4.2, 4.4, 5.0, 6.0, 7.0, and 8.0.

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 StackOverflow (using a "mongodb" tag).

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:

• 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.

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.

Installation

PyMongo can be installed with pip:

python -m pip install pymongo

You can also download the project source and do:

pip install .

Do not install the "bson" package from pypi. PyMongo comes with its own bson package; running "pip install bson" installs a third-party package that is incompatible with PyMongo.

Dependencies

PyMongo supports CPython 3.9+ and PyPy3.10+.

Required dependencies:

Support for mongodb+srv:// URIs requires dnspython

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]"

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 and pymongo-auth-aws:

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,zstd,encryption]"

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]
