1. os and shutil for File Operations

The os and shutil libraries are fundamental for automating file operations in Python. They provide functions to interact with the operating system and perform tasks like creating, deleting, and moving files and directories.

Example:

import os

import shutil

# Create a new directory

os.makedirs(‘new_directory’)

# Move a file

shutil.move(‘source.txt’, ‘new_directory/destination.txt’)

2. glob for File Pattern Matching

The glob library is useful for finding all the pathnames matching a specified pattern. It’s particularly handy when you need to work with multiple files that follow a certain naming convention.

Example:

import glob

# List all .txt files in the current directory

txt_files = glob.glob(‘*.txt’)

print(txt_files)

3. requests for HTTP Requests

The requests library simplifies the process of making HTTP requests. It’s ideal for tasks like downloading files, interacting with APIs, and web scraping.

Example:

import requests

# Download a web page

response = requests.get(‘https://example.com’)

print(response.text)

4. BeautifulSoup for Web Scraping

BeautifulSoup is a library for parsing HTML and XML documents. It works well with requests to scrape data from websites efficiently.

Example:

from bs4 import BeautifulSoup

# Parse HTML content

soup = BeautifulSoup(response.text, ‘html.parser’)

print(soup.title.string)

5. Selenium for Browser Automation

Selenium is a powerful tool for automating web browsers. It’s commonly used for web testing but can also automate web interaction tasks like form submission and navigation.

Example:

from selenium import webdriver

# Open a web browser and navigate to a page

driver = webdriver.Chrome()

driver.get(‘https://example.com’)

print(driver.title)

driver.quit()

6. pandas for Data Manipulation

pandas is an essential library for data manipulation and analysis. It provides data structures like DataFrames, which are perfect for handling structured data.

Example:

import pandas as pd

# Load data into a DataFrame

df = pd.read_csv(‘data.csv’)

print(df.head())

7. openpyxl for Excel Automation

openpyxl is a library for reading and writing Excel files. It’s perfect for automating tasks that involve Excel spreadsheets.

Example:

import openpyxl

# Load an Excel file

wb = openpyxl.load_workbook(‘data.xlsx’)

sheet = wb.active

print(sheet[‘A1’].value)

8. schedule for Job Scheduling

schedule is a simple library for scheduling tasks. It allows you to run Python functions at specified intervals, making it ideal for periodic automation tasks.

Example:

import schedule

import time

def job():

print(“Task running…”)

# Schedule a task to run every minute

schedule.every(1).minute.do(job)

while True:

schedule.run_pending()

time.sleep(1)

9. pyautogui for GUI Automation

pyautogui allows you to control the mouse and keyboard to automate interactions with GUI applications. It’s useful for tasks that require repetitive manual actions.

Example:

import pyautogui

# Move the mouse to (100, 100) and click

pyautogui.moveTo(100, 100)

pyautogui.click()

10. SMTP for Sending Emails

The smtplib library is used for sending emails using the Simple Mail Transfer Protocol (SMTP). It’s useful for automating email notifications and reports.

Example:

import smtplib

def send_email():

server = smtplib.SMTP(‘smtp.example.com’, 587)

server.starttls()

server.login(‘username’, ‘password’)

message = ‘Subject: {}\n\n{}’.format(‘Test’, ‘This is a test email.’)

server.sendmail(‘from@example.com’, ‘to@example.com’, message)

server.quit()

send_email()

Python’s extensive library ecosystem makes it a powerful tool for automating a wide variety of tasks.
