***Using a code cell under a Notebook***
{% endembed %}

You can write and execute code using the Notebook interface. This section covers the steps to write and run a sample code in the Code cell of the BDB DSL Notebook.

{% hint style="info" %}
*<mark style="color:green;">Please Note:</mark> A Code cell gets added by default while creating a new Notebook.*&#x20;
{% endhint %}

* Create a new Notebook and open it.
* A cell to write and execute code opens under the selected Notebook by default.

* Write code inside the cell.
* Click the ***Run cell*** icon to run the code.

{% hint style="info" %}
*<mark style="color:green;">Please Note:</mark> The Code cells also get code from the selected Notebook operations by using the right-side panel and selecting a specific option. E.g., the following image displays how the code for an available Dataset gets inserted while selecting the dataset.*

{% endhint %}

* The Run cell button gets changed into the Interrupt cell icon while running the code.
* Another code cell gets added below (as shown in the following image).

* Once the code has run successfully a checkmark appears below the Run cell icon.

* Click the ***Save*** icon provided for the Notebook.
* A notification message appears to indicate the completion of the action.

* *While the **Code** and **Markdown** options provided under the **Code** section of the Task Bar adds a new cell before the given code/Markdown cell.*
* *Refer the **Data Science Lab Quick Start Flow** page to get an overview of the **Data Science Lab** module in nutshell.* [***Click here***](https://docs.bdb.ai/data-science-lab/data-science-lab-quick-start-flow) *to get redirected to the quick start flow page.*
