How to change the color of points with special conditions in the dataframe

Question

I have a dataframe that includes students' id and grades in different subjects, and I want the lessons that have passed (> 10) to be shown in green and lessons that have been failed to be shown in red.

import pandas as pd
df=pd.DataFrame({"Math":[2,20,12,12,5,10,9.75,17],"Physics":[3,16,13,18,6,10,9,10],"chemistry":[10,19,5,17,16.5,14.75,10,4]},index=[331,332,333,334,335,336,337,338])

Answer 1

def colors(val):
    color = 'red' if val <= 10 else 'green'
    return 'color: %s' % color
df.style.applymap(colors)
