Install the Python client with pip:

Verify that pip is version 23.0 or higher:
```
pip --version
```
If needed, upgrade pip:
```
python -m pip install --upgrade pip
```
Install the astrapy package. You must have Python 3.8 or higher.
```
pip install astrapy
```

Connect to a vector-enabled Astra DB Serverless database

Create a file named quickstart.py with the following content:

quickstart.py

import os
from astrapy import DataAPIClient
from astrapy.constants import VectorMetric

# Initialize the client and get a "Database" object
client = DataAPIClient(os.environ["ASTRA_DB_APPLICATION_TOKEN"])
database = client.get_database(os.environ["ASTRA_DB_API_ENDPOINT"])
print(f"* Database: {database.info().name}\n")

Run the script with python quickstart.py.
