## Define a constant to use as a "document type"

We will use it later as a fixed field `type` in our documents.

This is not required by Couchbase, but is a good practice that will help you afterwards.

```Python hl_lines="9"
{!../../../docs_src/nosql_databases/tutorial001.py!}
```

## Add a function to get a `Bucket`

In **Couchbase**, a bucket is a set of documents, that can be of different types.

This can be very useful for setting up **resources** that you need to use for the whole app, and that are **shared** among requests, and/or that you need to **clean up** afterwards. For example, a database connection pool, or loading a shared machine learning model.

## Use Case

Let's start with an example **use case** and then see how to solve it with this.

collection. Once all such events have been sent, a synthetic \"Bookmark\" event  will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with `\"k8s.io/initial-events-end\": \"true\"` annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched.\n\nWhen `sendInitialEvents` option is set, we require `resourceVersionMatch` option to also be set. The semantic of...

                .build());
        options.addOption(Option.builder(FAIL_AT_END)
                .longOpt("fail-at-end")
                .desc("Only fail the build afterwards; allow all non-impacted builds to continue")
                .build());
        options.addOption(Option.builder(FAIL_NEVER)
                .longOpt("fail-never")

// Create an env var MY_NAME in line for this program call
$ MY_NAME="Wade Wilson" python main.py

// Now it can read the environment variable

Hello Wade Wilson from Python

// The env var no longer exists afterwards
$ python main.py

Hello World from Python
