# Pandas Data Automation Example
import pandas as pd
from datetime import datetime

# Read multiple data sources
sales_df = pd.read_excel("sales_data.xlsx")
customers_df = pd.read_csv("customers.csv")

# Clean and transform data
sales_df['date'] = pd.to_datetime(sales_df['date'])
sales_df = sales_df.dropna(subset=['amount'])

# Merge datasets
merged = pd.merge(sales_df, customers_df, on='customer_id')

# Generate summary report
summary = merged.groupby('region').agg({
    'amount': ['sum', 'mean', 'count'],
    'customer_id': 'nunique'
}).round(2)

# Export automated report
timestamp = datetime.now().strftime('%Y-%m-%d')
summary.to_excel(f'weekly_report_{timestamp}.xlsx')
print(f"Report generated: weekly_report_{timestamp}.xlsx")

from openpyxl.styles import Font, PatternFill, Alignment
from openpyxl.chart import BarChart, Reference

wb = Workbook()
ws = wb.active

# Add styled header
ws['A1'] = 'Sales Report'
ws['A1'].font = Font(bold=True, size=14)
ws['A1'].fill = PatternFill(start_color='3B82F6', fill_type='solid')

# Add data and create chart
data = [['Product', 'Sales'], ['Widget A', 150], ['Widget B', 200]]
for row in data:
    ws.append(row)

chart = BarChart()
chart.add_data(Reference(ws, min_col=2, min_row=2, max_row=4))
ws.add_chart(chart, 'D2')

wb.save('formatted_report.xlsx')

🧪 Pytest

Pytest is the most popular python automation framework for testing. It offers simple syntax, powerful fixtures, parametrization, and an extensive plugin ecosystem. Most Python projects use Pytest for unit, integration, and end-to-end testing.

# Parametrized test - runs multiple times with different data
@pytest.mark.parametrize("endpoint,expected_status", [
    ("/users", 200),
    ("/products", 200),
    ("/invalid", 404),
])
def test_api_endpoints(api_base, endpoint, expected_status):
    response = requests.get(f"{api_base}{endpoint}")
    assert response.status_code == expected_status

# Test with setup and teardown
class TestUserWorkflow:
    @pytest.fixture(autouse=True)
    def setup(self, api_base):
        self.api = api_base
        self.user_id = None

    def test_create_user(self):
        response = requests.post(f"{self.api}/users", json={"name": "Test"})
        assert response.status_code == 201
        self.user_id = response.json()['id']

    def test_get_user(self):
        response = requests.get(f"{self.api}/users/1")
        assert 'name' in response.json()

# API configuration
BASE_URL = "https://api.example.com"
API_KEY = "your_api_key_here"  # Use environment variables in production

headers = {
    "Authorization": f"Bearer {API_KEY}",
    "Content-Type": "application/json"
}

# GET request with parameters
response = requests.get(
    f"{BASE_URL}/users",
    headers=headers,
    params={"page": 1, "limit": 10}
)
users = response.json()

# POST request with JSON body
new_user = {"name": "John Doe", "email": "john@example.com"}
response = requests.post(
    f"{BASE_URL}/users",
    headers=headers,
    json=new_user
)

if response.status_code == 201:
    print(f"User created: {response.json()['id']}")
else:
    print(f"Error: {response.status_code}")

# Download file
file_response = requests.get(f"{BASE_URL}/reports/monthly.pdf")
with open("monthly_report.pdf", "wb") as f:
    f.write(file_response.content)

Installation: pip install requests

⚡ HTTPX

HTTPX is a modern alternative to Requests that supports async operations. For high-volume API automation in 2026, HTTPX offers better performance through concurrent requests.

# HTTPX Async API Automation
import httpx
import asyncio

async def fetch_all_users():
    async with httpx.AsyncClient() as client:
        # Concurrent requests - much faster than sequential
        tasks = [
            client.get(f"https://api.example.com/users/{i}")
            for i in range(1, 101)
        ]
        responses = await asyncio.gather(*tasks)
        return [r.json() for r in responses if r.status_code == 200]

# Run async automation
users = asyncio.run(fetch_all_users())
print(f"Fetched {len(users)} users concurrently")

Installation: pip install httpx

🍲 BeautifulSoup

BeautifulSoup is the go-to python library for automation tasks involving HTML parsing. Combined with Requests, it forms a powerful web scraping toolkit for extracting data from static websites.

# BeautifulSoup Web Scraping Example
import requests
from bs4 import BeautifulSoup
import pandas as pd

def scrape_product_data(url):
    headers = {'User-Agent': 'Mozilla/5.0'}
    response = requests.get(url, headers=headers)
    soup = BeautifulSoup(response.content, 'html.parser')

    products = []
    for item in soup.find_all('div', class_='product-card'):
        product = {
            'name': item.find('h2').text.strip(),
            'price': item.find('span', class_='price').text.strip(),
            'rating': item.find('div', class_='rating').get('data-rating'),
            'url': item.find('a')['href']
        }
        products.append(product)

    return pd.DataFrame(products)

# Scrape and save
df = scrape_product_data("https://example-store.com/products")
df.to_csv("products_data.csv", index=False)
print(f"Scraped {len(df)} products")

Installation: pip install beautifulsoup4 lxml

🕷️ Scrapy

Scrapy is a complete python automation framework for large-scale web scraping. It handles concurrent requests, data pipelines, and exports out of the box. Use Scrapy for complex scraping projects requiring multiple pages, authentication, or scheduled runs.

⏰ Schedule

Schedule is the simplest python automation tool for running tasks at intervals. Its human-readable syntax makes scheduling intuitive.

# Schedule Task Automation Example
import schedule
import time

def generate_daily_report():
    print("Generating daily report...")
    # Your automation code here

def check_emails():
    print("Checking emails...")
    # Email automation code

def backup_database():
    print("Backing up database...")
    # Backup automation code

# Schedule tasks with readable syntax
schedule.every().day.at("09:00").do(generate_daily_report)
schedule.every(30).minutes.do(check_emails)
schedule.every().sunday.at("02:00").do(backup_database)

# Run scheduler
print("Automation scheduler started...")
while True:
    schedule.run_pending()
    time.sleep(60)

Installation: pip install schedule

💡 Pro tip: For production automation, consider using system-level schedulers like cron (Linux/Mac) or Task Scheduler (Windows) combined with Python scripts. For complex workflows, look into Apache Airflow or Celery.
