# Streamlit Deployment

### Notebook Code

You need to create variables/objects needed in your Streamlit app in a notebook. This can be later reference in the streamlit app code.

For example, in the screenshot below a df called employees is created in a notebook block

<figure><img src="/files/OZjwyW5rfpMPf0BRxkJZ" alt=""><figcaption></figcaption></figure>

### Referencing variables

To reference a variable/object in the canvas use the following code:

```
from zerve import variable
name = variable ("block_name", "variable_name")
```

In the above example, our block name is employee\_data and the required df is stored as employees. In this example the code to reference the df is:

```
from zerve import variable
employees = variable ("employee_data", "employees")
```

### Instance Type

You can chose any instance type for your deployment.&#x20;

### Example

The following video shows how we can deploy the Streamlit app.
