This article explains how to retrieve a set of documents from a MongoDB collection using PyMongo, which is the Python driver for MongoDB.

The MongoDB overview explains the details of installing MongoDB, the Python Client library for MongoDB - PyMongo and creating documents, collections and databases.

Each document is like a record and each collection is like a table. Each collection of a MongoDB can hold multiple MongoDB documents.

Each MongoDB database can hold multiple MongoDB collections.

A MongoDB server can host multiple Mongo Databases.

MongoDB stores data as documents in the format of BSON -in other words the binary JSON.

To add multiple records simultaneously, a guide by Towards Data Science specifies using the “insert_many()” function. You may change collection_001 into any name you like.įor documents, you may use the “insert_one” function for a single entry. Your database will exist only if you’ve added collections and documents, so the next step is to create your collection by adding the command “collection_name = dbname” to your. The if _name_ line is added to enable multiple files to reuse the function get_database(). With this file, a database named product_list will be created.
