Format the color of a cell in a pandas dataframe according to multiple conditions

Question

I am trying to format the color of a cell of an specific column in a data frame, but I can\'t manage to do it according to multiple conditions.

This is my dataframe

Answer 1

Use applymap:

from datetime import datetime, timedelta
import pandas as pd

name = ['Diego', 'Luis', 'Vidal', 'John', 'Yusef']
id = ['b000000005', 'b000000015', 'b000000002', 'b000000011', 'b000000013']
cel = [7878, 6464, 1100, 4545, 1717]
date = pd.to_datetime(['2017-05-31 20:53:00', '2017-05-11 20:53:00', '2017-05-08 20:53:00', 
                       '2017-06-06 20:53:00', '2017-06-06 20:53:00'])

df = pd.DataFrame({'Name':name,'ID':id,'Cel':cel,'Date':date})

def color(val):
    if val < datetime.now():
        color = 'green'
    elif val > datetime.now():
        color = 'yellow'
    elif val > (datetime.now() + timedelta(days=60)):
        color = 'red'
    return 'background-color: %s' % color

df.style.applymap(color, subset=['Date'])

Screenshot from Jupyter notebook. If you print the output instead, you'll just get a reference to the Styler object:

print(df.style.applymap(color, subset=['Date']))
<pandas.formats.style.Styler object at 0x116db43d0>

Answer 2

The way it is written, no cells would be painted red. You should change the order, letting the condition to paint red before the one to paint yellow.
