Study Notes

Jupyter Notebook Overview

Jupyter Notebook is an open-source web application for creating and sharing documents with live code, equations, visualizations, and narrative text.
Popular in fields like data analysis, scientific research, machine learning, and education, primarily associated with Python programming.
Unique feature: integrates code and explanations via Markdown cells, enhancing understanding and communication of programming concepts.

Creating and Running Python Scripts

Launch Jupyter Notebook from terminal/command prompt using jupyter notebook.
Create a new notebook by clicking the "New" button and selecting "Python 3".
Write Python code in cells; code execution is done by pressing Shift + Enter, displaying results below the cell.
Use Markdown to add comments or explanatory text by changing cell type to "Markdown" in the dropdown menu.

Managing Cells

New cells can be added using the "+" button in the toolbar, and can be designated as "Code" or "Markdown".
Cells can be reordered using up/down arrows in the toolbar or command mode shortcuts (A for above, B for below).
To delete a cell, select it and press D twice while in command mode.
Entire notebooks can be executed using "Run All" from the "Cell" menu or by running cells individually.

Jupyter Notebook displays outputs like printed values, plots, and results directly below the respective code cell.
Saving can be done by clicking the save icon or navigating to "File" > "Save and Checkpoint".
Notebooks can be shared by exporting them to PDF/HTML or sharing the notebook file itself.
