# Using a Code Cell

Write & Run Code in a Notebook.

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 Data Science Notebook.

*<mark style="color:green;">Please Note:</mark> A Code cell gets added by default while creating a new .ipynb file. The above-given video displays inserting a new code cell to introduce the user other way to insert a code cell.*
{% endhint %}

## Running Code inside a Code Cell

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

* Load a dataset into the given .ipynb file.
* 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 user can use the Datasets tab to get an added data set to the code cell.*
{% endhint %}

* The ***Run*** cell button gets changed into the ***Interrupt cell*** icon while running the code.

* Once the code has run successfully a checkmark appears below the ***Run cell*** icon.
* Add new code cell gets added, insert the Show function in that cell.
* Run the code cell.
* The dataset preview appears below.

* Another code cell gets added below (as shown in the following image).
* Click the ***Save*** icon provided for the Notebook.

* A notification message appears to indicate the completion of the action.
* The Notebook status gets changed as saved and the new updates get saved in it.
