Most times, data analysts tend not to like the look and feel of the default theme of Jupyter notebook as this by default is a light theme. Not to worry here is a simple step on how to customize your Jupyter notebook.

How do I go about it?

The first thing you need to do is run this command on your Jupyter notebook !pip install jupyterthemes to install themes of Jupyter notebook.

Now that you've installed the themes library, let's see the list of themes that has been installed using this command ! jt -l

Available Themes: 
   chesterish
   grade3
   gruvboxd
   gruvboxl
   monokai
   oceans16
   onedork
   solarizedd
   solarizedl

To change the theme use this code and specify the theme name from the list of available themes. ! jt -t [theme name] -T -N -kl

Here, the theme used in this context is 'gruvboxd '

! jt -t gruvboxd -T -N -kl

However, if you have any need to restore the thems to its default thems, kindly run this code ! jt -r
