Using Markdown in Jupyter

Jupyter notebooks aren't just for code. They're for documentation and explanations, too! In this video, I show you how you can use Markdown to format cells in Jupyter, opening the door to including headlines, boldface, italic, bulleted lists, hyperlinks, and even images -- with a minimum of fuss. I write all about Python in my free, weekly "Better developers" newsletter, at BetterDevelopersWeekly.com/, currently read by more than 16,000 Python developers each week.

Never think of leaving YT. Very few can teach with so much efficiency. Even if someone has zero background he/she can understand what you've explained.

[@teklehaimanotaman3150]

Excellent teaching skills Reuven. How did you develop this amazing teaching and programming skills?

[@ReuvenLerner]

Thanks so much for your kind words! My "secret" is that I teach nearly every day, 4-8 hours per day. Over time, you make lots of mistakes, and try to learn from them. I often make the analogy to stand-up comedians, who try their jokes again and again and again, until they become smooth and effective (i.e., funny). I teach the same courses many times, and thus learn (often the hard way!) what explanations do and don't work.

Its awesomely helpful! I'm wondering if theres something similar in Pycharm though... Thx

[@ReuvenLerner]

Glad you enjoyed it! The idea of "cells" that can contain either code or Markdown is special to Jupyter. So if you're using PyCharm's paid (professional) edition, then you can fire up a notebook and use Markdown there. But in a regular ol' PyCharm (or Python) file, you can't.

[@vcstudios2974]

Thank you. Very helpful... And also, can we use even functions of python in a markdown cell?

[@ReuvenLerner]

Happy it's helpful! So far as I know, cells can either contain executable code or Markdown, but not both. So you'll have to choose which you want. That said, you can have Markdown cells just above and below your code cells, which is what I do.

[@birdvsbird6280]

How do you get in and out to show in the cell?

[@ReuvenLerner]

In is a list, and Out is a dict. They're global variables, which means that they're always available when you're in Jupyter. So you can just refer to them as In[n] or Out[n], where n is the index/key of the input/output you want to mention.

Jupyter is just like any other Web page. So if you want to make things bigger or smaller, you can increase/decrease your browser's magnification level. I do this all the time with command-plus and command-minus on my Mac; other systems will be slightly different.

Markdown is an easy way to write HTML, not equations. And I don't know whether Word supports Markdown, but I'm guessing that it doesn't. You can look into LaTeX (which I have mostly forgotten) for equations in Jupyter.

@@harithm9219 I don't think you can. Maybe if you start to insert raw HTML and/or CSS, you can get that sort of thing to happen.

How to change the color of the headings and sub-headings?

[@ReuvenLerner]

What a great question! I didn't know, so I looked it up, and ... I have bad news: Markdown doesn't support color. So officially, and sticking only with Markdown, you don't have any options. However, if you're willing to get your hands dirty a bit, you can use "font" tags in HTML to set colors. See fix.code-error.com/how-to-change-color-in-markdown-cells-ipython-jupyter-notebook/ for a simple example.

[@reemashrestha9718]

@@ReuvenLerner Yeah I saw that answer before. But the thing is, I couldn't use the css styling ( ) for Jupyter. Using every-time is tiring. Besides, one cannot use # inside . I was wondering if there is any other way to pre-define the setting of headings and sub-headings. Thanks for your effort. :) Great summary video.
