📉 The bitcoin is falling, boss! We will teach Python to monitor the cryptocurrency rate and notify if the rate is above or below the threshold. We will connect the requests library and import time:

import requests
import time

We will create a function to get the BTC price in USD via the CoinGecko API:

def get_btc_price():
    url = "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd"
    r = requests.get(url)
    return r.json()["bitcoin"]["usd"]

Now — the main monitoring cycle. We will set a threshold and check the price every minute:

threshold = 65000  # specify your goal
while True:
    price = get_btc_price()
    print(f"BTC: ${price}")
    if price > threshold:
        print("🚀 Time to sell!")
        break
    time.sleep(60)

🔥 You can also easily adapt it for Ethereum, DOGE, or even Telegram Token — just replace bitcoin with the desired coin in the URL.

Project ideas for Web Development 👆 💡 How many of these you have build already?

Sometimes reality outpaces expectations in the most unexpected ways. While global AI development seems increasingly fragmented, Sber just released Europe's largest open-source AI collection—full weights, code, and commercial rights included. ✅ No API paywalls. ✅ No usage restrictions. ✅ Just four complete model families ready to run in your private infrastructure, fine-tuned on your data, serving your specific needs. What makes this release remarkable isn't merely the technical prowess, but the quiet confidence behind sharing it openly when others are building walls. Find out more in the article from the developers. GigaChat Ultra Preview: 702B-parameter MoE model (36B active per token) with 128K context window. Trained from scratch, it outperforms DeepSeek V3.1 on specialized benchmarks while maintaining faster inference than previous flagships. Enterprise-ready with offline fine-tuning for secure environments. GitHub | HuggingFace GigaChat Lightning offers the opposite balance: compact yet powerful MoE architecture running on your laptop. It competes with Qwen3-4B in quality, matches the speed of Qwen3-1.7B, yet is significantly smarter and larger in parameter count. Lightning holds its own against the best open-source models in its class, outperforms comparable models on different tasks, and delivers ultra-fast inference—making it ideal for scenarios where Ultra would be overkill and speed is critical. Plus, it features stable expert routing and a welcome bonus: 256K context support. GitHub | Hugging Face Kandinsky 5.0 brings a significant step forward in open generative models. The flagship Video Pro matches Veo 3 in visual quality and outperforms Wan 2.2-A14B, while Video Lite and Image Lite offer fast, lightweight alternatives for real-time use cases. The suite is powered by K-VAE 1.0, a high-efficiency open-source visual encoder that enables strong compression and serves as a solid base for training generative models. This stack balances performance, scalability, and practicality—whether you're building video pipelines or experimenting with multimodal generation. GitHub | Hugging Face | Technical report Audio gets its upgrade too: GigaAM-v3 delivers speech recognition model with 50% lower WER than Whisper-large-v3, trained on 700k hours of audio with punctuation/normalization for spontaneous speech. GitHub | HuggingFace Every model can be deployed on-premises, fine-tuned on your data, and used commercially. It's not just about catching up – it's about building sovereign AI infrastructure that belongs to everyone who needs it.

How to Learn API Development? Learning how to develop APIs is an important skill for modern-day developers. Here’s a mind map of what all you need to learn about API development: 1 - API Fundamentals What is an API, types of API (REST, SOAP, GraphQL, gRPC, etc.), and API vs SDK. 2 - API Request/Response HTTP Methods, Response Codes, and Headers. 3 - Authentication and Security Authentication mechanisms (JWT, OAuth 2, API Keys, Basic Auth) and security strategies. 4 - API Design and Development RESTful API principles include stateless, resource-based URL, versioning, and pagination. Also, API documentation tools like OpenAPI, Postman, Swagger. 5 - API Testing Tools for testing APIs such as Postman, cURL, SoapUI, and so on. 6 - API Deployment and Integration Consuming APIs in different languages like JS, Python, and Java. Also, working with 3rd party APIs like the Google Maps API and the Stripe API. Learn about API Gateways like AWS, Kong, Apigee. Over to you: What else will you add to the list for learning API development?

Python Cheat Sheet: The Ternary Operator 🚀 Shorten your if/else statements for compact, one-line value selection. It's also known as a conditional expression. #### 📜 The Standard if/else Block This is the classic, multi-line way to assign a value based on a condition.

# Check if a user is an adult
age = 20
status = ""

if age >= 18:
    status = "Adult"
else:
    status = "Minor"

print(status)
# Output: Adult

--- #### ✅ The Ternary Operator (One-Line if/else) The same logic can be written in a single, clean line. Syntax: value_if_true if condition else value_if_false Let's rewrite the example above:

age = 20

# Assign 'Adult' if age >= 18, otherwise assign 'Minor'
status = "Adult" if age >= 18 else "Minor"

print(status)
# Output: Adult

--- 💡 More Examples The ternary operator is an expression, meaning it returns a value and can be used almost anywhere. 1. Inside a Function return

def get_fee(is_member):
    # Return 5 if they are a member, otherwise 15
    return 5.00 if is_member else 15.00

print(f"Your fee is: ${get_fee(True)}")
# Output: Your fee is: $5.0
print(f"Your fee is: ${get_fee(False)}")
# Output: Your fee is: $15.0

2. Inside an f-string or print()

is_logged_in = False

print(f"User status: {'Online' if is_logged_in else 'Offline'}")
# Output: User status: Offline

3. With List Comprehensions (Advanced) This is where it becomes incredibly powerful for creating new lists.

numbers = [1, 10, 5, 22, 3, -4]

# Create a new list labeling each number as "even" or "odd"
labels = ["even" if n % 2 == 0 else "odd" for n in numbers]
print(labels)
# Output: ['odd', 'even', 'odd', 'even', 'odd', 'even']

# Create a new list of only positive numbers, or 0 for negatives
sanitized = [n if n > 0 else 0 for n in numbers]
print(sanitized)
# Output: [1, 10, 5, 22, 3, 0]

--- 🧠 When to Use It (and When Not To!) • DO use it for simple, clear, and readable assignments. If it reads like a natural sentence, it's a good fit. • DON'T use it for complex logic or nest them. It quickly becomes unreadable. ❌ BAD EXAMPLE (Avoid This!):

# This is very hard to read!
x = 10
message = "High" if x > 50 else ("Medium" if x > 5 else "Low")

✅ BETTER (Use a standard if/elif/else for clarity):

x = 10
if x > 50:
    message = "High"
elif x > 5:
    message = "Medium"
else:
    message = "Low"

✅ Top 5 Mistakes to Avoid When Learning Python ❌🐍 1️⃣ Skipping the Basics Jumping into frameworks too early without mastering variables, loops, functions, and data types leads to confusion later. 2️⃣ Not Writing Enough Code Watching tutorials without coding won’t build skill. Always write and tweak the code yourself. 3️⃣ Ignoring Errors and Debugging Don’t just copy-paste fixes. Understand why the error happened. Use print() and read tracebacks carefully. 4️⃣ Avoiding Built-in Functions & Docs Python’s standard library is powerful. Learn to use zip(), enumerate(), map(), and read official docs regularly. 5️⃣ Skipping Projects Syntax alone won’t help. Build small projects like a calculator, to-do app, or web scraper to apply your knowledge. Bonus Tips from 2025 guides: ⦁ Don’t forget colons : at end of control statements (if, for, while) ⦁ Be mindful of data types and conversions ⦁ Use list comprehensions to simplify loops ⦁ Understand difference between print() and return 💬 Tap ❤️ for more Python tips! These tips come from Python learning resources in 2025 that emphasize practice and understanding over memorization. Ready to start a hands-on project? 😊
