What is Jupyter Notebook in Python?

Jupyter notebook is a free and open-source web application that allows interactive computing in over 40 programming languages. This blog post introduces the very basics of the jupyter notebook: how to install it, get started, use markdown, etc. Jupyter notebook is an open-source web-based application that lets users create and share documents with live formulas, code, and visualizations along with narrative and other text. This lets you create and distribute documents with live code, visuals as well as narrative text.

Let’s look at what constitutes the Jupyter notebooks. It is a web-based interactive computing platform. The notebook is a combination of live code equations, narrative texts visualizations interactive dashboards, as well as other types of media. The application provides a portable development environment for data science projects. It can be used in a classroom setting, a corporate data science group, or a scientific research group. It provides an environment where we can write the code in Python (or R) along with the description of what the code does using Markdown language. We can also add visualizations to support our explanation of the topic we are writing about. 

What is Jupyter?

Jupyter is a project that lets you create notebooks that can embed live code, text, and graphics in many languages. Jupyter is a command-line interface that permits you to execute code straight in your browser. It’s an excellent tool for data scientists and programmers because it will enable them to see both the code and the results of their work side by side. It’s also helpful in writing tutorials and reports since you can explain and demonstrate how the code works at the same time instead of having to switch back and forth between the documentation and the code itself.

Jupyter Notebook VS Jupyter Lab

Jupyter notebook vs. jupyter lab – what’s the difference? In this article, we explore the differences between Jupyter Notebook and Jupyter Lab. So you can determine which one will be best for you. To properly examine the differences between the two, let’s go over the essential features that both have in common. Both are based on Python, they’re open-source, and they can be used in a variety of different programming languages. They also both provide an integrated development environment (IDE). This lets you write, run and debug code right in your browser.

Jupyter Notebook is an older version of Jupyter that was launched in 2015. It was created with Python but can be used to process R, Julia, and Scala code as well. The interface mimics a regular electronic notebook, and it allows users to organize their code into cells within a single file. Jupyter Lab is essentially an upgraded version of the Jupyter Notebook that was released in 2018. It has all the same features as Jupyter Notebook but with some added enhancements, including improved styling. It also supports multiple programming languages such as C++, Julia, and MATLAB.

What is Jupyter Notebooks used for?

Using Jupyter notebooks in your notebook instance to prepare and process data, write code to train models, deploy models to Amazon SageMaker hosting, and test or validate your models? Uses contain data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more. 

Online jupyter notebook– Online jupyter notebook is a new technology that allows you to use a jupyter notebook without installing it on your local machine. It is available at https://jupyter.org/try. The main reason to use an online jupyter is that it gives all the functionality of a jupyter without the need for installing it and maintaining the environment required for running a jupyter notebook.

How does Jupyter Notebook work?

It is a server-client system that allows you to easily combine text, code, and graphics in a single document. It’s perfect for those who are just starting with data science or for experienced data scientists who want to share their work.

How to Share Jupyter Notebooks?

Share notebook is a feature of Jupyter notebook to share your notebook. To share a jupyter notebook, follow these steps:

1. Open your notebook in Jupyter Notebook

2. Click on File and then click on Share or Publish Notebook

3. Select Github from the dropdown menu, which will appear next to Publish button, as shown in the picture below:

4. After selecting Github, the commit message textbox appears; enter your commit message, and click on Publish.

5. Now open the GitHub website, and you will find your repository containing your files (if you are using GitHub for the first time, you need to create a new repository)

6. Finally, go to settings and make it public. Otherwise, it will be visible only to you

Benefits of using Jupyter Notebook

In a friendly tone:  Jupyter notebook is a very powerful and popular platform for data analysis. It is compatible with many programming languages. It comes with various advantages, which makes it more practical than other platforms. Let’s have a look at some of the advantages of using the Jupyter notebook

Easy to use

Jupiter notebook is easy to use. You just need to download Anaconda and install it on your system, and you are ready to go. You can efficiently run any program in a jupyter notebook.

Compatible with many languages

This web application is compatible with various languages like Python, Julia, R, Racket, etc. This provides flexibility to the user to choose his favorite language for coding purposes. This feature makes the jupyter notebook an essential tool for data analysis.

Markdown support

This application supports markdown formatting also. It makes documentation easier by providing all the features of markdown formatting in addition to writing code and outputs.

Converting your jupyter notebook into other formats

The application supports over 40 programming languages (python, R, Scala, etc.). It also allows you to convert your jupyter notebook into other formats such as HTML or pdf, which can be easily shared with others.

Sharing your work with others

You can easily share your jupyter notebook with others using email or dropbox. They can view the contents of the notebook without installing any additional software on their computers.

Excellent visualization capabilities

Jupyter notebooks have excellent visualization capabilities which allow you to see what’s going on inside your code at any given time

Downsides of using Jupyter Notebook

The downside of using Jupyter Notebook is that it’s not suitable for every type of person. It isn’t as convenient to use as other software like Sublime Text or Vim. This means that people who are more comfortable working with Vim could be forced to use something else, which would make them less productive. It also means they might need to spend more time learning how the new software works instead of just focusing on coding in it.

Another downside is that it doesn’t have syntax highlighting for Python or C++, which are two common languages gets in use by programmers today. This makes it harder for these users to see what kind of code they’re writing at a glance and can lead them down paths where their code won’t run correctly because they’ve made mistakes without noticing them right away.

Jupyter Notebook is not a reliable data storage tool; If you plan to store something in your notebook, it could be a good idea to save a backup somewhere else. The reason is that notebooks are stored as JSON files which you can open in any text editor and see what they contain.

There is no way to directly store Python objects in the notebook file; it only stores the code that can generate those objects. So if your Python code isn’t working properly, there will be no way of recovering the data you stored in that notebook file. 

Availability of Jupyter Notebook

Jupyter Notebook is available in two forms, first as a standalone application on the desktop and second as a server-based tool in the cloud. The desktop version runs on the most common operating systems (Windows, Mac OS X, Linux). So you’ve probably covered no matter which computer(s) you use. Installing it is quick and easy; just download and run the installer (here’s where you can get that). The server-based version relies on a web browser to interact with it.

You need to have a server running somewhere for this to work. If you already have a web server running somewhere, you can install Jupyter Notebook on that system and use your existing connection to access it anywhere. If you don’t have a web server available, then we recommend using Amazon Web Services (AWS) to host your Jupyter Notebook instance. AWS offers free use of its servers for new users.

Databricks Offer Support for Jupyter

Databricks announced that the company is offering support for Jupyter Notebooks. It is often utilize for data cleaning and transformation, numerical simulation, statistical modeling, machine learning, and much more. Databricks also supports Scala, Python, R, and SQL. Databricks said the company’s implementation of Jupyter Notebooks is fully integrate with the rest of its platform. This means users can now use the same platform to run their production data pipelines as they do their interactive data exploration and model development workflows.

“With this new release, we are bringing together some of the best parts of the Notebook ecosystem with an enterprise-ready platform to enable data science teams to scale to today’s big data volumes while maintaining ownership of key assets,” said Ali Ghodsi, CEO at Databricks. “This allows companies to move faster because their teams can easily collaborate on solutions for their toughest challenges.” Databricks’ Cloud-based implementation supports Apache Spark jobs with up to 100x faster performance than Hadoop MapReduce in memory and 10x faster on disk.
