Overview of Jupyter IDE and Python 3 Notebook

3 Important Coding Tips

  • Depth knowledge about the IDE which we are using it. This makes our work easier.
  • Debugging skill. This particular skill will reduce a lot of coding efforts especially while fixing issues.
  • Use Google search effectively - Apply trial and error method for issue fixing.

  • What is Jupyter Notebook?

  • Jupyter Notebook was born out of IPython in 2014
  • The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, mathematics, visualizations and narrative text.
  • Services for interactive computing across dozens of programming languages.

  • Use of Jupyter Notebook

  • Data cleaning and transformation
  • Numerical simulation
  • Statistical modeling
  • Data visualization
  • Machine learning

  • Jupyter Notebook Features

  • In-browser editing for code, with automatic syntax highlighting, indentation, and tab completion/introspection.
  • The ability to execute code from the browser, with the results of computations attached to the code which generated them.
  • Displaying the result of computation using rich media representations, such as HTML, LaTeX, PNG, SVG, etc. For example, publication-quality figures rendered by the matplotlib library, can be included inline.
  • In-browser editing for rich text using the Markdown markup language, which can provide commentary for the code, is not limited to plain text.
  • The ability to easily include mathematical notation within markdown cells using LaTeX, and rendered natively by MathJax.

  • Open Jupyter Notebook

    Search for Command Prompt and open it

    Type "jupyter notebook" and press Enter

  • It will take few minutes to load and finally it will display the URL details.
  • The URL will be Autolaunched in the default browser as per your computer settings.
