Did you know about .background_gradient()? Before today no, I did not!

I did not ... and now I do! And that thanks to a tweet from Karina Bartolomé and the screen capture below:

What is .background_gradient()?

It is a styling format from the library pandas in Python.

If you want to know more and read the documentation, you can follow this link https://pandas.pydata.org/docs/reference/api/pandas.io.formats.style.Styler.background_gradient.html

Pandas is one of the library I recommend you to install on my article How to import python libraries

Example from the tweet

If you want to copy/paste this coe, I reproduced it for you below:

Copycopy code to clipboard
1import pandas as pd
2
3df = pd.read_csv('https://github.com/datasciencedojo/datasets/blob/master/titanic.csv')
4
5(df 
6  .groupby
7  .agg(
8    n = ('PassengerId','count')
9    survivors = ('Survived','sum')
10    p_survivors = ('Survived','mean')
11  )
12  .style
13  .background_gradient(subset=['p_survivors'], vmin=0, vmax=1, cmap='colorwarn_r')
14  .background_gradient(subset=['n','survivors'], cmap='blues')
15)

For the purpose of this example, it was done using a Python Notebook
