# Python Program 1: Hello World - For Beginners
print('Hello, World!')

# Python Program 2: Simple Calculator - Intermediate Level
def simple_calculator():
    print('Simple Calculator')
    print('Options: 
1. Addition
2. Subtraction
3. Multiplication
4. Division')
    choice = input('Choose operation (1/2/3/4): ')
    
    num1 = float(input('Enter first number: '))
    num2 = float(input('Enter second number: '))

    if choice == '1':
        print(f'{num1} + {num2} = {num1 + num2}')
    elif choice == '2':
        print(f'{num1} - {num2} = {num1 - num2}')
    elif choice == '3':
        print(f'{num1} * {num2} = {num1 * num2}')
    elif choice == '4':
        if num2 != 0.0:
            print(f'{num1} / {num2} = {num1 / num2}')
        else:
            print('Error: Cannot divide by zero.')
    else:
        print('Invalid choice')

# Python Program 3: Web Scraper - Advanced Level
import requests
from bs4 import BeautifulSoup

def web_scraper(url):
    response = requests.get(url)
    soup = BeautifulSoup(response.text, 'html.parser')
    
    for link in soup.find_all('a'):
        href = link.get('href')
        text = link.string
        print(f'Link: {href}, Text: {text}')

# Call the functions
print('
--- Simple Calculator ---')
simple_calculator()

print('
--- Web Scraper ---')
web_scraper('http://example.com')

Code Output:

Code Explanation:

The Python code snippet included three different programs targeting users from beginners to advanced levs.

For Beginnrs:

• Hello World Program: A simple print statement that teaches the basic convention of displaying output in Python.

For Intermediate Users:

• Simple Calculator: This functional calculator allows the user to choose an operation (addition, subtraction, multiplication, division) and perform it on two input numbers. The if-elif-else conditional checks for the operation selected by the user and computes accordingly. It also handles the division by zero case to avoid runtime errors.

For Advanced Users:

• Web Scraper: Utilizing the requests and BeautifulSoup libraries, this program fetches HTML content of a given URL and extracts all hyperlinks along with the text associated with them. It’s a basic introduction to web scraping, a powerful technique for data extraction from websites.

The structure of the code demonstrates the progression in complexity and utility of Python scripts, making it perfect for learners with varying degrees of experience in programming. Each program showcases fundamental concepts such as output display, user input handling, conditionals, and working with external libraries for more complex tasks like web scraping.
