#### Five Python Code Examples Here are five Python code examples that cover different aspects of the language: 1. **Hello World**: ```python print("Hello, World!") ``` This is a simple example that prints the phrase "Hello, World!" to the console. It is often used as a starting point for learning a new programming language. 2. **Factorial Calculation**: ```python def factorial(n): if n == 0: return 1 else: return n * factorial(n-1) result = factorial(5) print(result) ``` This example demonstrates a recursive function to calculate the factorial of a number. It defines a function called `factorial` that takes an integer `n` as input and returns the factorial of `n`. The code then calls the `factorial` function with the argument `5` and prints the result. 3. **List Comprehension**: ```python numbers = [1, 2, 3, 4, 5] squares = [x**2 for x in numbers] print(squares) ``` This example shows how to use list comprehension to create a new list that contains the squares of the numbers in the original list. It defines a list called `numbers` and uses list comprehension to create a new list called `squares` where each element is the square of the corresponding element in `numbers`. The code then prints the `squares` list. 4. **File Handling**: ```python with open("example.txt", "r") as file: content = file.read() print(content) ``` This example demonstrates how to read the contents of a file in Python. It uses the `open` function to open a file called "example.txt" in read mode, and then uses the `read` method to read the entire content of the file into a variable called `content`. The code then prints the `content` variable. 5. **Web Scraping**: ```python import requests from bs4 import BeautifulSoup url = "https://www.example.com" response = requests.get(url) soup = BeautifulSoup(response.content, "html.parser") print(soup.title.text) ``` This example shows how to perform web scraping using Python. It imports the `requests` library to send an HTTP request to a URL and the `BeautifulSoup` library to parse the HTML content of the response. The code then extracts the title of the web page and prints it. These examples cover a range of Python concepts and can serve as a starting point for learning and exploring the language further.
