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 2.6, 3.0, 3.2, 3.4, 3.6 and 4.0.
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.
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.
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, ...)
If you’ve identified a security vulnerability in a driver or any other MongoDB project, please report it according to the instructions here.
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.
PyMongo supports CPython 2.7, 3.4+, PyPy, and PyPy3.5+.
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]
Support for mongodb+srv:// URIs requires dnspython:
$ python -m pip install pymongo[srv]
TLS / SSL support may require ipaddress and certifi or wincertstore depending on the Python version in use. The necessary dependencies can be installed along with PyMongo:
$ python -m pip install pymongo[tls]
Wire protocol compression with snappy requires python-snappy:
$ python -m pip install pymongo[snappy]
You can install all dependencies automatically with the following command:
$ python -m pip install pymongo[snappy,gssapi,srv,tls]
Other optional packages:
- backports.pbkdf2, improves authentication performance with SCRAM-SHA-1 and SCRAM-SHA-256. It especially improves performance on Python versions older than 2.7.8.
- monotonic adds support for a monotonic clock, which improves reliability in environments where clock adjustments are frequent. Not needed in Python 3.
Additional dependencies are:
- (to generate documentation) sphinx
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
u'test'
>>> db.my_collection
Collection(Database(MongoClient('localhost', 27017), u'test'), u'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()
{u'x': 10, u'_id': ObjectId('4aba15ebe23f6b53b0000000')}
>>> for item in db.my_collection.find():
... print(item["x"])
...
10
8
11
>>> db.my_collection.create_index("x")
u'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]
You will need sphinx installed to generate the documentation. Documentation can be generated by running python setup.py doc. Generated documentation can be found in the doc/build/html/ directory.
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
