This is a ready to use instance of [CosmosClient](https://docs.microsoft.com/python/api/azure-cosmos/azure.cosmos.cosmos_client.cosmosclient?view=azure-python) from our Python SDK. It already has the context of this account baked in. We'll use ```cosmos_client``` to create a new database called **RetailDemo** and container called **WebsiteData**.\n\nOur dataset will contain events that occurred on the website - e.g. a user viewing an item, adding it to their cart, or purchasing it. We will partition by CartId, which represents the individual cart of each user. This will give us an even distribution of throughput and storage in our container. Learn more about how to [choose a good partition key.](https://docs.microsoft.com/azure/cosmos-db/partition-data)"
