MongoDB — Python

Installation

pip install pymongo

Connect

from pymongo import MongoClient

client = MongoClient('mongodb://localhost:27017')
db = client['mydb']

CRUD Operations

# Insert
db.users.insert_one({"name": "John", "email": "john@example.com"})

# Find
users = db.users.find({"active": True})

# Update
db.users.update_one({"name": "John"}, {"$set": {"age": 30}})

# Delete
db.users.delete_one({"name": "John"})

PyMongo

# Insert many
db.users.insert_many([
    {"name": "Jane", "email": "jane@example.com"},
    {"name": "Bob", "email": "bob@example.com"}
])

# Find with query
users = db.users.find({"age": {"$gt": 25}})

# Sort
users = db.users.sort("name", 1)  # 1=asc, -1=desc

Motor (Async)

from motor.motor_asyncio import AsyncIOMotorClient

client = AsyncIOMotorClient('mongodb://localhost:27017')
db = client['mydb']

async def insert_user():
    await db.users.insert_one({"name": "John"})

Mini Practice

1. Connect with PyMongo
2. Perform CRUD operations
3. Use queries
4. Try async with Motor
