Reverse column order in pandas

# Import modules
import pandas as pd

# Example dataframe

raw_data  = {'fruit': ['Banana', 'Orange', 'Apple', 'lemon', "lime", "plum"], 
        'color': ['yellow', 'orange', 'red', 'yellow', "green", "purple"], 
        'kcal': [89, 47, 52, 15, 30, 28]
    }

df = pd.DataFrame(raw_data, columns = ['fruit', 'color', 'kcal'])
df

	fruit	color	kcal
0	Banana	yellow	89
1	Orange	orange	47
2	Apple	red	52
3	lemon	yellow	15
4	lime	green	30
5	plum	purple	28

The columns of a dataframe can be reversed by using the loc accessor and passing :,::-1. The : before the , means select all rows and the ::-1 after the , means reverse the column order

df.loc[:,::-1]

	kcal	color	fruit
0	89	yellow	Banana
1	47	orange	Orange
2	52	red	Apple
3	15	yellow	lemon
4	30	green	lime
5	28	purple	plum
