\subsection{Introduction}\label{introduction}
Jupyter Notebooks are often used for data science and scientific
computing such as machine learning as the interactive design allow you
to experiment easily with your code. For our purpose, we will use
Notebooks as it's a useful tool to learn how to code as well as writing
reports.
\emph{Note on the difference between Notebook and Lab: Jupyter Notebook
offers a simplified, lightweight notebook authoring experience, where
as, JupyterLab offers a feature-rich, tabbed multi-notebook editing
environment with additional tools like a customizable interface layout
and system console}
\subsection{Setup and Installation}\label{setup-and-installation}
Installing with Conda using CLI: - \texttt{conda\ install\ jupyter}
Jupyter can also be installed using a Anaconda Navigator
\begin{verbatim}
- Launching:
- From terminal: `jupyter notebook` or `jupyter lab`
- From Anaconda Navigator or VSCode
- Navigating the interface:
- Tabs and file browser
- Kernel and terminals
\end{verbatim}
\subsection{Notebook Basics}\label{notebook-basics}
\begin{itemize}
\tightlist
\item
Creating a new notebook (\texttt{.ipynb})
\item
Types of cells:
\begin{itemize}
\tightlist
\item
Code
\item
Markdown
\item
Raw
\end{itemize}
\item
Running a cell: \texttt{Shift\ +\ Enter}
\item
Adding/removing cells
\item
Restarting the kernel
\item
Saving and auto-checkpoints
\end{itemize}
\subsection{Writing and Running Code}\label{writing-and-running-code}
\begin{itemize}
\tightlist
\item
Python syntax: - \texttt{print("Hello,\ world!")} - Variables and
functions - Loops and conditionals
\item
Importing libraries: - \texttt{import\ numpy\ as\ np} -
\texttt{import\ pandas\ as\ pd} -
\texttt{import\ matplotlib.pyplot\ as\ plt}
\end{itemize}
\subsection{Using Markdown}\label{using-markdown}
\begin{itemize}
\tightlist
\item
Headers: \texttt{\#}, \texttt{\#\#}, \texttt{\#\#\#}
\item
Bullet lists: \texttt{-\ item}
\item
Numbered lists: \texttt{1.\ item}
\item
Emphasis: \emph{italic}, \textbf{bold}, \texttt{monospace}
\item
LaTeX equations:
\begin{itemize}
\tightlist
\item
Inline: \texttt{\$E\ =\ mc\^{}2\$}
\item
Block:
\texttt{\$\$\textbackslash{}int\_0\^{}\textbackslash{}infty\ e\^{}\{-x\^{}2\}\ dx\ =\ \textbackslash{}frac\{\textbackslash{}sqrt\{\textbackslash{}pi\}\}\{2\}\$\$}
\end{itemize}
\item
Embedding links and images
\end{itemize}
\subsection{Interactive Widgets
(optional)}\label{interactive-widgets-optional}
Install \texttt{ipywidgets} from your package manager
\begin{Shaded}
\begin{Highlighting}[]
\ImportTok{import}\NormalTok{ ipywidgets }\ImportTok{as}\NormalTok{ widgets}
\NormalTok{widgets.IntSlider()}
\end{Highlighting}
\end{Shaded}
Example using interact:
\begin{Shaded}
\begin{Highlighting}[]
\ImportTok{from}\NormalTok{ ipywidgets }\ImportTok{import}\NormalTok{ interact}
\NormalTok{interact(}\KeywordTok{lambda}\NormalTok{ x: x}\OperatorTok{**}\DecValTok{2}\NormalTok{, x}\OperatorTok{=}\DecValTok{5}\NormalTok{)}
\end{Highlighting}
\end{Shaded}
\subsection{Productivity Tips}\label{productivity-tips}
Here are some keyboard shortcuts to improve your productivity when
writing in notebooks.
\begin{longtable}[]{@{}ll@{}}
\toprule\noalign{}
Key & Action \\
\midrule\noalign{}
\endhead
\bottomrule\noalign{}
\endlastfoot
A & insert cell above \\
B & insert cell below \\
M & switch to Markdown \\
Y & switch to code \\
\end{longtable}
Magic commands: - \texttt{\%timeit}, \texttt{\%matplotlib\ inline},
\texttt{\%\%bash} Splitting and merging cells Auto-save behavior
\subsection{Exporting and Sharing}\label{exporting-and-sharing}
