Jupyter Markdown Formatting

To get markdown formatted output, you can use the Markdown object of the display machinery. A print-like function could thus look like from IPython.display import Markdown, display def printmd (string): display (Markdown (string)) printmd ('.bold.'). Markdown allows arbitrary HTML code for formatting. Markdown attachments Since Jupyter notebook version 5.0, in addition to referencing external file. Explore and run machine learning code with Kaggle Notebooks Using data from no data sources. Formatting code outputs. Many libraries support their own HTML output formatting, and this generally carries over to Jupyter Book outputs as well. For example, the following cell uses Pandas to format cells based on their values. Markdown ¶ Markdown output is. You also learned how to change the default type of the cell by clicking in the cell and selecting a new cell type (e.g. Markdown) in the cell type menu in the toolbar.Furthermore, you learned that in a Jupyter Notebook file, you can double-click in any Markdown cell to see the syntax, and then run the cell again to see the Markdown formatting. Note: if you type text in a Markdown cell with no.

Introduction¶

Jupyter has a beautiful notebook that lets you write and execute code, analyze data, embed content, and share reproducible work. Jupyter Notebook (previously referred to as IPython Notebook) allows you to easily share your code, data, plots, and explanation in a sinle notebook. Publishing is flexible: PDF, HTML, ipynb, dashboards, slides, and more. Code cells are based on an input and output format. For example:

Installation¶

There are a few ways to use a Jupyter Notebook:

• Install with pip. Open a terminal and type: $ pip install jupyter.
• Windows users can install with setuptools.
• Anaconda and Enthought allow you to download a desktop version of Jupyter Notebook.
• nteract allows users to work in a notebook enviornment via a desktop application.
• Microsoft Azure provides hosted access to Jupyter Notebooks.
• Domino Data Lab offers web-based Notebooks.
• tmpnb launches a temporary online Notebook for individual users.

Getting Started¶

Once you've installed the Notebook, you start from your terminal by calling $ jupyter notebook. This will open a browser on a localhost to the URL of your Notebooks, by default http://127.0.0.1:8888. Windows users need to open up their Command Prompt. You'll see a dashboard with all your Notebooks. You can launch your Notebooks from there. The Notebook has the advantage of looking the same when you're coding and publishing. You just have all the options to move code, run cells, change kernels, and use Markdown when you're running a NB.

Helpful Commands¶

- Tab Completion: Jupyter supports tab completion! You can type object_name.<TAB> to view an object’s attributes. For tips on cell magics, running Notebooks, and exploring objects, check out the Jupyter docs.
- Help: provides an introduction and overview of features.

- Quick Reference: open quick reference by running:

- Keyboard Shortcuts:Shift-Enter will run a cell, Ctrl-Enter will run a cell in-place, Alt-Enter will run a cell and insert another below. See more shortcuts here.

Languages¶

The bulk of this tutorial discusses executing python code in Jupyter notebooks. You can also use Jupyter notebooks to execute R code. Skip down to the [R section] for more information on using IRkernel with Jupyter notebooks and graphing examples.

Package Management¶

When installing packages in Jupyter, you either need to install the package in your actual shell, or run the ! prefix, e.g.:

You may want to reload submodules if you've edited the code in one. IPython comes with automatic reloading magic. You can reload all changed modules before executing a new line.

Some useful packages that we'll use in this tutorial include:

• Pandas: import data via a url and create a dataframe to easily handle data for analysis and graphing. See examples of using Pandas here: https://plotly.com/pandas/.
• NumPy: a package for scientific computing with tools for algebra, random number generation, integrating with databases, and managing data. See examples of using NumPy here: https://plotly.com/numpy/.
• SciPy: a Python-based ecosystem of packages for math, science, and engineering.
• Plotly: a graphing library for making interactive, publication-quality graphs. See examples of statistic, scientific, 3D charts, and more here: https://plotly.com/python.

Import Data¶

You can use pandas read_csv() function to import data. In the example below, we import a csv hosted on github and display it in a table using Plotly:

Use dataframe.column_title to index the dataframe:

Most pandas functions also work on an entire dataframe. For example, calling std() calculates the standard deviation for each column.

Plotting Inline¶

You can use Plotly's python API to plot inside your Jupyter Notebook by calling plotly.plotly.iplot() or plotly.offline.iplot() if working offline. Plotting in the notebook gives you the advantage of keeping your data analysis and plots in one place. Now we can do a bit of interactive plotting. Head to the Plotly getting started page to learn how to set your credentials. Calling the plot with iplot automaticallly generates an interactive version of the plot inside the Notebook in an iframe. See below:

Plotting multiple traces and styling the chart with custom colors and titles is simple with Plotly syntax. Additionally, you can control the privacy with sharing set to public, private, or secret.

Now we have interactive charts displayed in our notebook. Hover on the chart to see the values for each bar, click and drag to zoom into a specific section or click on the legend to hide/show a trace.

Plotting Interactive Maps¶

Plotly is now integrated with Mapbox. In this example we'll plot lattitude and longitude data of nuclear waste sites. To plot on Mapbox maps with Plotly you'll need a Mapbox account and a Mapbox Access Token which you can add to your Plotly settings.

3D Plotting¶

Using Numpy and Plotly, we can make interactive 3D plots in the Notebook as well.

Animated Plots¶

Checkout Plotly's animation documentation to see how to create animated plots inline in Jupyter notebooks like the Gapminder plot displayed below:

Plot Controls & IPython widgets¶

Add sliders, buttons, and dropdowns to your inline chart:

Additionally, IPython widgets allow you to add sliders, widgets, search boxes, and more to your Notebook. See the widget docs for more information. For others to be able to access your work, they'll need IPython. Or, you can use a cloud-based NB option so others can run your work.

Executing R Code¶

IRkernel, an R kernel for Jupyter, allows you to write and execute R code in a Jupyter notebook. Checkout the IRkernel documentation for some simple installation instructions. Once IRkernel is installed, open a Jupyter Notebook by calling $ jupyter notebook and use the New dropdown to select an R notebook.

See a full R example Jupyter Notebook here: https://plotly.com/~chelsea_lyn/14069

Additional Embed Features¶

We've seen how to embed Plotly tables and charts as iframes in the notebook, with IPython.display we can embed additional features, such a videos. For example, from YouTube:

LaTeX¶

We can embed LaTeX inside a Notebook by putting a $$ around our math, then run the cell as a Markdown cell. For example, the cell below is $$c = sqrt{a^2 + b^2}$$, but the Notebook renders the expression.

Or, you can display output from Python, as seen here.

Exporting & Publishing Notebooks¶

Jupyter Notebook Markdown Math Symbols List

We can export the Notebook as an HTML, PDF, .py, .ipynb, Markdown, and reST file. You can also turn your NB into a slideshow. You can publish Jupyter Notebooks on Plotly. Simply visit plot.ly and select the + Create button in the upper right hand corner. Select Notebook and upload your Jupyter notebook (.ipynb) file!The notebooks that you upload will be stored in your Plotly organize folder and hosted at a unique link to make sharing quick and easy.See some example notebooks:

Publishing Dashboards¶

Users publishing interactive graphs can also use Plotly's dashboarding tool to arrange plots with a drag and drop interface. These dashboards can be published, embedded, and shared.

Publishing Dash Apps¶

For users looking to ship and productionize Python apps, dash is an assemblage of Flask, Socketio, Jinja, Plotly and boiler plate CSS and JS for easily creating data visualization web-apps with your Python data analysis backend.
