How do I handle errors in Python when using MongoDB?

You can handle errors in Python with MongoDB by using try-except blocks. This allows you to catch exceptions that may occur during database operations.

Can you give me an example of using try-except with MongoDB?

Sure! Here's a simple example:

from pymongo import MongoClient, errors

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

try:
    db.mycollection.insert_one({'name': 'Alice'})
except errors.PyMongoError as e:
    print(f'An error occurred: {e}')

What types of errors should I be aware of?

You should be aware of connection errors, operation errors, and validation errors. Each of these can be caught using specific exception classes in PyMongo.

Is there a way to log these errors for later review?

Yes, you can use Python's logging module to log errors. Just configure the logger and log the exception in the except block.
