Python Learning Timeline: A Realistic Guide

Most Python beginners don’t know this simple trick. You can swap two numbers in just one line. Without using a third variable. Example: x = 10 y = 20 x, y = y, x Now: x = 20 y = 10 Simple. Clean. Pythonic. This is why many developers love Python. Less code. More clarity. 👉 Did you know this Python trick before?

Do you know the difference between @staticmethod and @classmethod in Python? Most beginners use one or the other without fully understanding why. @staticmethod does not receive any implicit argument. It belongs to the class only for organisational purposes — it could live anywhere, but it makes sense to keep it there. @classmethod receives the class itself as the first argument, conventionally called cls. This means it can access and modify class-level data. The rule is simple: if the method needs the class, use @classmethod. If it needs nothing, use @staticmethod. In the image below you can see both methods applied to the same class. validate_email does not need to know anything about the class — it just validates a string. increment_count needs access to user_count, which belongs to the class itself, not to any specific instance. 💭 Have you ever used one when you should have used the other? #Python #Backend #PythonDeveloper #BuildingInPublic #HKingsJourney

 Python fundamentals are not just beginner topics you move past -- they are the mental models you rely on every time you write code... https://lnkd.in/g2U7xidG #python

List comprehension is a powerful feature in Python that helps you write short, clean, and efficient code. Instead of using long loops, you can do the same task in just one line. 💡 Example: Create a list of squares from 1 to 10 👉 [x*x for x in...

Ever wondered how Python solves calculations? 🤔 It follows a simple rule called Order of Operations (PEMDAS) OR rules of precedence 👍 Quick challenge 👇 What will this return? 👉 6 + 4 / 2 = ?

Just released a5_fast 🚀 Python bindings using PyO3 for a5 Rust library 🦀 https://lnkd.in/gU_7Mqfs If you're working with A5 in Python, give it a spin. It should be considerably faster than native Python implementations. 🐍 https://lnkd.in/gdgd5Wsf #Rust #Python #PyO3 #OpenSource #A5

Every import in #Python executes the module, from start to finish. Meaning? Big modules slow down your program's startup time. Coming in Python 3.15 this October: "lazy import", which delays the load until a name is used: lazy import MODULE lazy from MODULE import NAME

There's never been a better time to learn core Python. Sure, AI is writing code for us now. But you still need to understand it, review it, guide the AI to what you really want English is great but can be ambiguous. A glance at the Python code helps you ensure the AI understood your requirements, or quickly steer it in the right direction. Python fundamentals take you further today than they ever did in the past. Beware of skipping the basics…

I would like to share this moment with you: I have successfully published my first Python project. It is a simple cookbook and can be installed using the following link: https://lnkd.in/dQU_QQSA
