How to restart the kernel in Python?

In Jupyter Notebook, you can restart the Python kernel by following these steps:

1. Select the Kernel option in the menu bar.
2. Select “Restart” from the dropdown menu that appears.
3. Confirm the option in the pop-up dialog box and click “Restart”.

In Jupyter Lab, you can restart the Python kernel by following these steps:

1. Locate the running Python kernel in the “Running Terminals and Kernels” tab on the left.
2. Click on the “Restart” button next to the kernel.

In this way, you can restart the Python kernel, and your code will start running from the beginning. Please note that this will clear all previous variables and states, so make sure to save your work before restarting.
