Computer Programming

Knowing how many CPU cores your computer has can be very helpful. It lets your programs use all the available power to run tasks faster and smarter. For example, if you want to run several tasks at the same time, it’s good to know how many cores you can use. Luckily, Python makes this easy. […]

Type conversion overloading in Python means making your custom classes work smoothly with built-in conversion functions like int(), float(), bool(), and str(). By defining special methods, you tell Python how to convert your objects to these basic types whenever needed. This ability makes your objects behave more like built-in types, so you can use them

In Python, container methods let your custom classes behave like built-in containers such as lists, dictionaries, and sets. By overloading these special methods, your objects can support features like len(), in, indexing ([]), and iteration (for loops) in a natural and readable way. This makes your classes easier to work with, since they respond to

Assignment operators like +=, -=, and *= are commonly used in Python to update a variable by applying an operation directly to it. These operators perform what’s called in-place operations, meaning they try to modify the object itself instead of creating a new one. Python gives you the power to customize how these assignment operators

Bitwise operators are special symbols that work on individual bits of numbers. They let you combine, change, or check bits directly. In Python, these operators include & (AND), | (OR), ^ (XOR), << (left shift), and >> (right shift). Python lets you customize how these operators work on your own classes by using special methods

In Python, comparison operators like ==, !=, <, >, <=, and >= don’t just work with numbers—they can also be taught to work with your own custom classes. This is called comparison operator overloading. Instead of writing something like book1.compare(book2), you can simply write book1 == book2 or book1 < book2. This makes your code

In Python, unary operators are special symbols or functions that work with just one operand. You’ve probably seen them used with numbers: But what if you’re working with custom classes, like a Temperature or a Vector, and you want to use the same kind of expressions? Python allows you to overload unary operators using special

In Python, operator overloading allows you to define how built-in operators like +, -, *, or / behave when used with objects of your own classes. Instead of relying on method calls like vector1.add(vector2), you can write expressions such as vector1 + vector2, making your code more readable and intuitive. This feature is especially useful

Python is more than just a language for writing code—it’s a powerful tool for automation, scripting, and system integration. One of its most useful capabilities is the ability to run external programs directly from your Python scripts. This becomes essential when you need to: Whether you’re building developer utilities, scripting deployment processes, or simply chaining

In Python, a nonlocal variable is one that comes from an outer (but not global) function. When you use the nonlocal keyword, you tell Python, “Hey, I want to change that outer variable, not create a new one.” Why does this matter? Because sometimes, you want a nested function to remember and update something —
