Python continues to dominate the tech space with its simplicity, readability, and powerful features. Whether you’re just starting out or looking to sharpen your skills, here’s a quick breakdown of some essential Python concepts.

💻 What is Python in Computer Science?

Python is a high-level, interpreted programming language known for its easy-to-read syntax. It’s used in web development, AI, data science, automation, and more.

👉 It’s beginner-friendly, making it a favorite for new programmers and tech enthusiasts.

🧬 Python Metaclass — The Class Behind the Class

In Python, everything is an object — even classes. A metaclass defines how classes behave. 

class Meta(type):
    def __new__(cls, name, bases, dct):
        print(f'Creating class {name}')
        return super().__new__(cls, name, bases, dct)

Metaclasses are an advanced feature, but they offer deep control for frameworks and libraries.

🚫 NameError in Python

Ever seen this? 

print(my_variable)  # NameError: name 'my_variable' is not defined

This error occurs when you try to use a variable that hasn’t been defined yet. Always check your spelling and scope!

🆕 What’s New in the Latest Python Version?

Each new Python release introduces improved performance, cleaner syntax, and powerful features.

Some highlights in recent versions:

  • Pattern matching (match...case)
  • Type hinting enhancements
  • Faster CPython interpreter

Stay updated with the latest Python news to keep your skills fresh.

🔢 Working with Numbers in Python

Python handles all kinds of numbers with ease:

  • Integers: int
  • Floating points: float
  • Complex numbers: complex

a = 10
b = 3.14
c = 1 + 2j
