So, before we can think of plotting anything, we need to be able to walk the directory tree of a specific folder and gather the results of what subfolders and files exist within it. What if we could write a Python script that would be able to walk through a specific directory and retrieve the name of all the subfolders and files contained within it, and then query the search results to be able to plot a chart that summarizes these entries, by file extension? It is very easy with Python to be able to loop through all the subfolders and files of a specific directory tree. Python is a great language to work with folders and files. Information within a computer system is organized into folders, subfolders and files. Walking and Organizing a Folder Structure So, let’s go ahead and do something really interesting, which is to analyze the content of a directory tree.
JUPYTER NOTEBOOK TUTORIAL CODE
It’s about being able to write code in an interactive way. It’s about being able to add snippets of code and seeing what result each snippet returns. In essence, this is what a Jupyter Notebook is all about. We can add further code on the new cell and keep interacting with Python by pressing Shift+Enter and repeating the process, but with different snippets of code. This returned the value of 5 as the result of the operation and also added a new cell below. The instruction print(2+3) has been added to the cell and then Shift+Enter has been pressed. Within cells we can write snippets of code and see the results of the execution of that code, immediately. Notice the section highlighted in blue, which is known as a cell. Let’s go to that tab to start adding some code. This will open a new browser tab which will display the new Notebook. You can do this by clicking on the New button, and then clicking on the Python 3 option, as we can see below. Creating a New Notebookįrom the Jupyter Notebook main screen create a new notebook which to start developing an interactive Python solution. ipynb extension) can be saved and executed from.
Jupyter Notebook runs in the browser, and the main screen displays a list of local folders on your machine where Jupyter files (with the the. This command will execute Jupyter Notebook and open it in a browser window, which we can see as follows. Once the installation process has finished, we can launch Jupyter Notebook by running the command jupyter notebook, which we can also see below.
JUPYTER NOTEBOOK TUTORIAL INSTALL
To install Jupyter Notebook go to the command line (or terminal on your Mac) and run the pip install jupyter command, which we can see as follows. The technology is particularly well-suited for data analysis and plotting.

ipynb file extension.Ī great aspect of a Jupyter Notebook is that it can be converted to a number of different formats, such as: HTML, slides, PDF, Markdown and even Python through the “ Download As ” option available in the web interface.Ī Jupyter Notebook is a great way to build step-by-step interactive Python programs. Jupyter Notebook is a web-based interactive development environment for creating notebook documents, which are essentially a step-by-step incarnation of a Python program, through an interactive layout.Ī notebook may serve as a reference for many different entities, mainly the Jupyter web application, Jupyter Python web server, or Jupyter document format depending on the context.Ī Jupyter Notebook document is a JSON document, following a schema, and contains a list of input and output ordered cells that can contain code, Markdown text, mathematical expressions, plots, charts, and media.
