Pandas HR database: Display the name, salary and department number for those employees whose first name does not contain the letter 'M'

Pandas HR database Queries: Exercise-7 with Solution

Write a Pandas program to display the first, last name, salary and department number for those employees whose first name does not contain the letter 'M'.

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      Salary    Department ID")

result = employees[employees['first_name'].str.find('M')==-1]
for index, row in result.iterrows():
    print(row['last_name'].ljust(15),row['first_name'].ljust(15),str(row['salary']).ljust(9),row['department_id'])


Sample Output:
