20. Sort by Multiple Columns

Write a Pandas program to import given excel data (employee.xlsx ) into a Pandas dataframe and sort based on multiple given columns. Go to Excel data

Sample Solution:

Python Code :

import pandas as pd
import numpy as np
df = pd.read_excel('E:\employee.xlsx')
result = df.sort_values(by=['first_name','last_name'],ascending=[0,1])
result

Sample Output:

    emp_id   first_name   last_name  hire_date
