Write a Python script that connects to a MongoDB database, creates a new collection called "products", and inserts sample data into the collection. The sample data should include at least 10 products with fields like name, price, and description.

First, you need to install the `pymongo` library if you haven't already. You can do this by running:

```bash
pip install pymongo
```

Now, you can use the following Python script to connect to a MongoDB database, create a new collection called "products", and insert sample data into the collection.

```python
from pymongo import MongoClient

# Replace the placeholders with your actual MongoDB connection details.
mongo_uri = "mongodb+srv://<username>:<password>@cluster0.mongodb.net/test?retryWrites=true&w=majority"
client = MongoClient(mongo_uri)

# Connect to the database (replace 'my_database' with your desired database name)
db = client.my_database

# Create a new collection called 'products'
products = db.products

# Sample data for 10 products
sample_data = [
    {"name": "Product 1", "price": 9.99, "description": "This is product 1"},
    {"name": "Product 2", "price": 19.99, "description": "This is product 2"},
    {"name": "Product 3", "price": 29.99, "description": "This is product 3"},
    {"name": "Product 4", "price": 39.99, "description": "This is product 4"},
    {"name": "Product 5", "price": 49.99, "description": "This is product 5"},
    {"name": "Product 6", "price": 59.99, "description": "This is product 6"},
    {"name": "Product 7", "price": 69.99, "description": "This is product 7"},
    {"name": "Product 8", "price": 79.99, "description": "This is product 8"},
    {"name": "Product 9", "price": 89.99, "description": "This is product 9"},
    {"name": "Product 10", "price": 99.99, "description": "This is product 10"}
]

# Insert the sample data into the 'products' collection
result = products.insert_many(sample_data)

# Print the inserted IDs to confirm successful insertion
print("Inserted IDs:", result.inserted_ids)
```

Make sure to replace `<username>`, `<password>` and `my_database` with your actual MongoDB connection details and desired database name.

After running this script, you should see a new collection called "products" in your MongoDB database with the sample data inserted.
