Keyboard Shortcut to Clear Cell Output in Jupyter Notebook

As a data scientist, you are likely spending a lot of time working in Jupyter Notebook. This powerful tool allows you to create and share documents that contain live code, equations, visualizations, and narrative text. However, sometimes your output can get cluttered, and you need a quick and easy way to clear it. That’s where keyboard shortcuts come in. In this post, we’ll discuss the keyboard shortcut to clear cell output in Jupyter Notebook and why it’s so important.

The Importance of Clearing Output

Before we dive into the keyboard shortcut, let’s discuss why clearing output is so important in Jupyter Notebook. When you run a code cell, it generates output, which can include text, tables, plots, and more. Over time, the output can accumulate and make it difficult to read and understand your code. Clearing the output allows you to start fresh and focus on the current state of your notebook.

Additionally, when you share your notebook with others, you want to make sure that they see the most current and relevant output. Clearing the output before sharing can help ensure that your audience is not distracted by old or irrelevant information.

The Keyboard Shortcut to Clear Cell Output

Now that we’ve established the importance of clearing output, let’s discuss the keyboard shortcut to do so. In Jupyter Notebook, you can clear the output of a cell by using the “Esc” key followed by the “O” key. Here’s how it works:

1. Select the cell whose output you want to clear.
2. Press the “Esc” key to enter command mode.
3. Press the “O” key to clear the output of the selected cell.

That’s it! With just two keystrokes, you can clear the output of a cell and start fresh.

Other Keyboard Shortcuts for Jupyter Notebook

While we’re on the topic of keyboard shortcuts, it’s worth noting that Jupyter Notebook has many other shortcuts that can help you be more productive. Here are a few of the most commonly used shortcuts:

• “Shift + Enter": Run the current cell and move to the next cell.
• “Ctrl + Enter": Run the current cell and stay on the same cell.
• “A": Insert a new cell above the current cell.
• “B": Insert a new cell below the current cell.
• “D, D": Delete the current cell.
• “M": Change the current cell to a Markdown cell.
• “Y": Change the current cell to a code cell.

By learning and using these shortcuts, you can save time and be more efficient when working in Jupyter Notebook.

Conclusion

In conclusion, as a data scientist, clearing output in Jupyter Notebook is an important task that can help you stay organized and focused on your current work. The keyboard shortcut to clear cell output is “Esc” followed by “O”, and it’s a quick and easy way to clear the output of a cell. Additionally, Jupyter Notebook has many other keyboard shortcuts that can help you be more productive. By learning and using these shortcuts, you can save time and be more efficient in your work.
