df.describe() – Returns descriptive statistics for the entire data table. df.head() – Returns the first five lines of the data table, helping you get a better understanding of your data. When working with data in Python, it’s very convenient to see the output of separate code lines or code snippets. Using Python notebooks is especially popular in data science, where they make the workflow so much easier and more efficient. It doesn’t look like a complex Python program that only programmers can understand, but rather like a ready-to-be-shared report that is easy to follow. It has all the code, data, and visualizations nicely organized and structured. Display the code output, including data tables and charts, between the corresponding code snippets.Īs a result, you get a single document corresponding to your Python project. Write one or more lines of code and, if necessary, run each line separately to see the output immediately and spot any issues. Instead of writing and rewriting entire Python programs, you can use notebooks for a more interactive experience. Python) and rich text elements such as paragraphs of text, equations, visualizations, links, etc. Jupyter Notebook (formerly IPython Notebooks) is a web-based interactive computational environment that you can use to create documents that contain both computer code (e.g. 
With 141 coding challenges, it covers key topics that you’ll need to work with data in Python. If you don’t have much experience with Python yet, you may want to start with our interactive online course Introduction to Python for Data Science. In this article, I’ll discuss what a notebook is, how to install a Jupyter Notebook on your computer, how to work with notebooks, and when to use them. There are several popular Python IDEs for data science, but if you follow this field for a while, you’ll notice that many data scientists choose to carry on their projects in Jupyter Notebooks. It is also one of the key tools used in data science these days. Python is a general-purpose programming language that can be used for just about anything. Let’s explore what a notebook is and how to use notebooks in Python.
When reading or watching Python tutorials online, you might notice that many data scientists use Python notebooks for their projects.
