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.
EMPLOYEES.csv
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
Equivalent SQL Syntax:
SELECT first_name, last_name, salary, department_id FROM employees WHERE department_id IN (70 , 90);

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
