Pandas HR database Queries: Exercise-17 with Solution

Write a Pandas program to display the first name, last name, salary and department number for employees who works either in department 70 or 90.

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("First name      Last name       Salary    Department ID")
result = employees[employees['department_id'].isin([70, 90])]

for index, row in result.iterrows():
    print(row['first_name'].ljust(15),row['last_name'].ljust(15),str(row['salary']).ljust(9),row['department_id'])

Sample Output:

First name      Last name       Salary    Department ID
Steven          King            24000     90.0
Neena           Kochhar         17000     90.0
Lex             De Haan         17000     90.0
Hermann         Baer            10000     70.0

SELECT first_name, last_name, salary, department_id
 FROM employees
  WHERE department_id IN (70 , 90);
