• Kernel: A computational engine that executes the code within a notebook.
• Cell: A section within the notebook where code is written and executed by the kernel. When the code runs, the
output appears directly below the corresponding code cell.
Some of the important tasks you can do using Jupyter Notebook's tool bar are:
Icon Name Function
Save and create checkpoints It saves the code written in a notebook.
Insert a cell below It adds a cell next to an active cell.
Cut this cell It is used to cut the content of the selected cell.
Copy this cell It is used to copy the content of the selected cell.
Paste this cell from the clipboard It is used to paste the copied content.
Run this cell and advance It is used to execute the selected cell.
Interrupt the kernel It stops the execution of the selected cell.
Jupyter Notebook has a Menu bar which provides all its important functions within different menu options.
Let us have a look at some of the important options used for doing Python programming in Jupyter
Notebook. Let us study about them in detail.
File Menu
Some of the options available in File Menu are:
• Creates a New Notebook.
• Open an already created Notebook.
• Make another copy of an existing Notebook.
• Save As a new Notebook.
• Rename an existing Notebook.
• Save and Checkpoint option helps you create checkpoints that you can roll
back to if you need to.
