After setting up your client library and creating a client object, you can explore more to start working with your client.

## Create a client with multiple advertised listeners

To ensure clients in both internal and external networks can connect to a Pulsar cluster, Pulsar introduces [advertisedListeners](concepts-multiple-advertised-listeners.md).

The following example creates a Python client using multiple advertised listeners:


````mdx-code-block
<Tabs groupId="lang-choice"
  defaultValue="Java"
  values={[{"label":"Java","value":"Java"},{"label":"Python","value":"Python"}]}>
  <TabItem value="Java">

  ```java
  PulsarClient client = PulsarClient.builder()
    .serviceUrl("pulsar://xxxx:6650")
    .listenerName("external")
    .build();
  ```

  </TabItem>
  <TabItem value="Python">

  ```python
  import pulsar

  client = pulsar.Client('pulsar://localhost:6650', listener_name='external')
  ```

  </TabItem>
</Tabs>
