When working with parallel programming in Python, especially using the multiprocessing module, it’s important to understand how new processes are created. Python supports different ways to start a process, known as start methods. Each method controls how the new process begins and what it inherits from the parent. In this article, we’ll focus on the […]

Process pools are a way to manage many worker processes in Python without having to create and control each one yourself. Instead of starting processes one by one, you create a pool that handles them for you. This makes running many tasks in parallel easier and cleaner. Executors are a higher-level tool built on top

A daemon process in Python is a background process that runs alongside your main program. Unlike regular processes, a daemon process automatically stops as soon as the main program ends. This makes daemon processes perfect for tasks that need to run quietly in the background without keeping the program alive. For example, you might use

In Python, process-based parallelism means running different parts of your program at the same time in separate processes. Each process runs independently with its own memory, like workers in different rooms handling tasks without interfering with one another. Python’s built-in multiprocessing module makes it simple to create and manage these separate processes. This lets you

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
