Coding Examples: Real‑World Code You Can Use Now

Looking for code you can copy, paste, and adapt? You’re in the right place. This page gathers the most useful coding examples from our blog, so you can solve a problem today instead of searching forever.

Every example is short, concrete, and ready to run. Whether you want to add a simple AI feature, clean up a Python script, or squash a tricky bug, you’ll find a snippet that fits.

Quick Wins for Python and AI

Python still dominates AI work because it’s easy to read and has a massive library ecosystem. In our "Python Tricks: Practical Tips to Become a Better Python Developer in 2025" post, we show how to add type hints, use dataclasses, and profile code with cProfile. Copy the snippet below to see type hints in action:

def add_numbers(a: int, b: int) -> int:
    return a + b

print(add_numbers(3, 5))  # 8

If you want to call an OpenAI model without dealing with the API details, try the one‑liner in "Coding for AI: A Practical Guide to Build, Ship, and Scale AI Features in 2025":

response = openai.ChatCompletion.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Explain tokenizers"}]
).choices[0].message.content
print(response)

Run it, tweak the prompt, and you have a basic chatbot component in minutes.

Debugging & Productivity Hacks

Debugging takes time, but a few habits cut the effort in half. In "Code Debugging: Master the Skill Every Developer Needs" we recommend turning on breakpoint() instead of printing everywhere. Here’s a quick demo:

def calculate_total(items):
    total = 0
    for item in items:
        breakpoint()  # Execution stops here, inspect variables
        total += item['price'] * item['qty']
    return total

When the debugger stops, you can check item and total without adding print() statements.

Another productivity gem comes from "Programming Tricks: Ultimate Guide for Aspiring Developers to Code Faster and Smarter". Use the Ctrl+P shortcut in most IDEs to jump directly to a file. Combine it with a good folder naming convention and you’ll spend less time hunting files.

Because many of our readers work on AI projects, we also share a common error‑handling pattern for model inference:

try:
    result = model.predict(data)
except Exception as e:
    logger.error(f"Model failed: {e}")
    result = fallback_value

This tiny block catches time‑outs, missing files, or mis‑shaped inputs, keeping your service up.

All the examples above are just a taste. Browse the full list of posts under the "coding examples" tag to discover more snippets for web scraping, data cleaning, and even interview prep. Each article ends with a ready‑to‑run code block, so you can copy it straight into your project.

Ready to level up? Pick a snippet, tweak a variable, and see the result instantly. The more you experiment, the faster you’ll turn these examples into your own tools.
