```

</div>

<div data-language="python" markdown="1">
```python
#!/usr/bin/env python

import zulip

# Download ~/zuliprc-dev from your dev server
client = zulip.Client(config_file="~/zuliprc-dev")

# Send a stream message
client.send_message({
    "type": "stream",
    "to": "Denmark",
    "subject": "Castle",
    "content": "Something is rotten in the state of Denmark."
})

```
</div>

<div data-language="zulip-send" markdown="1"> You can use `zulip-send`
(available after you `pip install zulip`) to easily send Zulips from
the command-line, providing the message content via STDIN.

```bash
zulip-send --stream Denmark --subject Castle \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5
```

#### Passing in the message on the command-line

If you'd like, you can also provide the message on the command-line with the `-m` flag, as follows:


```bash
zulip-send --stream Denmark --subject Castle \
    -m "Something is rotten in the state of Denmark." \
    --user othello-bot@example.com --api-key a0b1c2d3e4f5a6b7c8d9e0f1a2b3c4d5
```

You can omit the `user` and `api-key` arguments if you have a `~/.zuliprc` file.
