To take advantage of the latest features and improvements in Python, it is important to keep your Jupyter Notebook updated with the latest Python version. This article will guide you through the process of updating Jupyter Notebook to the latest Python version.

Note: Let’s say if we want to Download Install from Python 3.7 to 3.11:

Checking the Current Python Version

Open Jupyter Notebook and run the following code in a cell:

import sys
print(sys.version)

Output

1. Update to the Latest Python Version Using Pip (For Windows)

Download and install the latest stable Python version from the official website. Make sure to select the correct installer for the operating system.

Updating Jupyter Notebook

Updating Python might not automatically update Jupyter Notebook. Use pip to update Jupyter Notebook:

pip install --upgrade jupyter

Output:

• Check the box next to Jupyter Notebook to update it.
• Click ‘Apply’.

Updating Jupyter Notebook using Commands

conda update -c conda-forge jupyterlab

Verifying the Update
