Practical Python Scripts for Beginners: From Hello World to Mini Games

This tutorial presents a collection of practical Python scripts designed for absolute beginners. It starts with the iconic "Hello, World!" program, then moves on to a simple calculator, a number‑guessing game, rock‑paper‑scissors, a to‑do list manager, a basic web scraper, a weather app, and many other useful utilities.

Each script is accompanied by a concise explanation that relates programming concepts to everyday analogies, making the material easy to understand.

<code># Hello, World! program print("Hello, World!")</code>

<code># Simple calculator num1 = float(input("Enter first number: ")) num2 = float(input("Enter second number: ")) operator = input("Enter operator (+, -, *, /): ") if operator == "+": result = num1 + num2 elif operator == "-": result = num1 - num2 elif operator == "*": result = num1 * num2 elif operator == "/": if num2 == 0: print("Cannot divide by zero") else: result = num1 / num2 else: print("Invalid operator") if "result" in locals(): print("Result:", result)</code>

<code># Guess the number game import random number = random.randint(1, 100) guess = 0 while guess != number: guess = int(input("Guess a number between 1 and 100: ")) if guess < number: print("Too low, try again!") elif guess > number: print("Too high, try again!") else: print("Congratulations, you guessed it!")</code>

<code># Rock‑paper‑scissors game import random choices = ["石头", "剪刀", "布"] computer_choice = random.choice(choices) user_choice = input("Enter your choice (石头, 剪刀, 布): ") print("Your choice:", user_choice) print("Computer's choice:", computer_choice) # ... determine winner ...</code>

<code># To‑do list manager todo_list = [] while True: action = input("Enter action (add, view, exit): ") if action == "add": item = input("Enter task: ") todo_list.append(item) elif action == "view": for item in todo_list: print(item) elif action == "exit": break else: print("Invalid action")</code>

<code># Basic web scraper import requests from bs4 import BeautifulSoup url = "https://www.example.com" response = requests.get(url) soup = BeautifulSoup(response.content, "html.parser") title = soup.title.string print("Page title:", title) links = soup.find_all("a") for link in links: print(link.get("href")) # pip install requests beautifulsoup4</code>

<code># Simple weather app (requires API key) import requests city = input("Enter city: ") api_key = "YOUR_API_KEY" url = f"http://api.weatherapi.com/v1/current.json?key={api_key}&q={city}" response = requests.get(url) weather_data = response.json() if "current" in weather_data: temperature = weather_data["current"]["temp_c"] condition = weather_data["current"]["condition"]["text"] print(f"{city} temperature: {temperature}°C, condition: {condition}") else: print("Failed to retrieve weather information") # pip install requests</code>

Additional scripts cover topics such as prime number checking, Fibonacci sequence generation, password generation, email scheduling, file organization, QR‑code creation, batch renaming, a simple HTTP server, and YouTube video downloading, providing a well‑rounded introduction to Python's capabilities.

By following these examples, readers can quickly build confidence in writing Python code and gain a solid foundation for further learning.
