Borrow and Build: Unlocking New Skills Through Code Reuse 👀

[new2code]

Raise your hand if you have ever gotten stuck in a project, then solved your problem with code you found online? ✋

I know I have! Whether you’re new to coding or a seasoned developer, integrating existing code into your projects can help you save time, explore new techniques, and build on the work of others.

Check out our new GitHub Docs Learn to code series, where today we’re exploring Reusing other people's code in your projects to help new developers learn the ropes for code reuse. We'll learn by working through an example: reusing Python code that calculates the factorial of a number. 🐍

Need a taster? Below are our favourite takeaways 🥡
But don’t forget to check out the full article as we’ll be asking you to answer questions in the comments 👇

🏃‍♂️ Accelerate Your Learning:

Copying and pasting code snippets is a great way to jumpstart your projects and understand new coding styles. Always start by finding a snippet that matches your needs, then study how it works before integrating it into your project.

❓Did you ask Copilot to explain the program?
5️⃣ points if you did 👍 Pic or we don’t believe you, post in the comments 😉

🔖 Respect Licensing:

Before using any code, check its license (like the MIT license in our example) to know your rights and responsibilities. This not only keeps your project legally sound but also supports ethical coding practices.

❓Using the “Choose a license” tool in the article, what are the “conditions” differences between GNU LGPLv3 and MIT License?
1️⃣ point for each correct condition.

✨ Customize and Grow:

Transform copied code into something uniquely yours! Convert snippets into functions tailored to your project. In our example we adapt a simple factorial calculator into a dynamic tool for multiple calculations. 👨‍🔬

❓Can you customize our factorial calculator into a different calculator?
5️⃣0️⃣ points if you share it in the comments 🎉

🛞 Leverage Libraries for Efficiency:

Instead of reinventing the wheel, import libraries to access well-tested, secure functions. This approach not only streamlines your development process but also enhances your project’s reliability. Let’s see how we can use Copilot to search for usable libraries.

❓What Python libraries does Copilot Chat suggest for machine learning?
🔟 points if you share the top two in the comments 🏅

🔒 Embrace Security Practices:

Using popular libraries and enabling tools like Dependabot alerts help safeguard your projects from vulnerabilities. Regularly check for updates and security advisories to maintain robust code.

❓Dependabot is available to what type of projects on GitHub?
5️⃣ points + 1️⃣5️⃣ points if you also share Dependabot PR from your own project

Wow, that was certainly a feast. We hope y’all followed along with the example in the article!

Share your completed factorial calculator project in the comments and tally up your points 🔢🥇 We can’t wait to see what modifications you came up with! 💖

This count as a custom? Multiple calculations and cache your inbetween results hehe

factorial_cache = {0: 1, 1: 1}

def calculate_factorial(number):
    if number in factorial_cache:
        return factorial_cache[number]

    # Find the highest cached value
    highest_cached = max(factorial_cache.keys())

    # Start calculating from the highest cached value + 1
    factorial = factorial_cache[highest_cached]
    for i in range(highest_cached + 1, number + 1):
        factorial *= i
        factorial_cache[i] = factorial

    return factorial_cache[number]

def factorial_of(number):

for i in range(1, number + 1):
start *= i

return start 

print( factorial_of(4))
