Pandas HR database Queries: Exercise-5 with Solution

Write a Pandas program to display the first and last name, and department number for all employees whose last name is "McEwen".

Sample Solution :

Python Code :

import pandas as pd
employees = pd.read_csv(r"EMPLOYEES.csv")
departments = pd.read_csv(r"DEPARTMENTS.csv")
job_history = pd.read_csv(r"JOB_HISTORY.csv")
jobs = pd.read_csv(r"JOBS.csv")
countries = pd.read_csv(r"COUNTRIES.csv")
regions = pd.read_csv(r"REGIONS.csv")
locations = pd.read_csv(r"LOCATIONS.csv")
print("Last name  First name    Department ID")
result = employees[employees.last_name == 'McEwen']
for index, row in result.iterrows():	
    print(row['last_name'],'   ',row['first_name'],'       ',row['department_id'])
