This guide will introduce you to the Python decimal library and class – Python tools which allow you to accurately work with decimal numbers without the rounding and accuracy issues which frequently arise when working with floating point numbers. Computers Can’t Perform Accurate Arithmetic With Decimal Numbers Decimal numbers are commonly stored as floating point number values. Computers are not particularly good at performing arithmetic with this type of numbers accurately. We break down why this is in our Ultimate Beginners Guide to Floating Point Math/Arithmetic Precision Problems. … Read more

This article will give a short overview of the Python os (Operating System) module – and show some examples of how it is used. What is the Python ‘os’ Library/Module? The Python os library contains helpful tools and functions for interacting with the underlying Operating System being used to execute the running Python code. It can be used to query information about the system environment – including operating system, disk space, memory information, and which path Python is being executed from. The information available will differ depending on which operating system Python is … Read more

This website is called LinuxScrew.com so I’ll get the obvious out of the way: the best OS for Python development is Linux. Here’s why. Why Linux is the Best OS to Develop Python Apps? …because Linux is the preferred OS of many, many other developers. That may seem like a silly statement – however – consider that the developer writing the tutorial you are going to use to learn to write Python code will be using Linux, you want to be able to enter the same commands and use … Read more

This article will show you how to update Python to the latest version on your Linux Operating system. Python is updated yearly with new features and big upgrades – these are called major updates. In addition to this, monthly updates are released which fix small issues and improve security – these are called minor updates. Major updates change how Python works a bit and may break compatibility with some code as features are added or removed, whereas minor updates are solely there to fix problems without altering any functionality. Updating From Python 2 … Read more

This article explains XOR (Exclusive Or) – what it is, why it’s used, and how to implement it in the Python programming language. What is XOR / Exclusive OR XOR – Exclusive Or – is a logical operation commonly used in computer programming. Logically, an XOR condition is true only if the supplied arguments differ. XOR compares two inputs and outputs, true or false, only if they are different. Those inputs are usually true/false boolean values or the result of a logical operation that returns a boolean value. For example, XOR on two values – 1 and 1 is false – they do not differ. XOR on two values … Read more

This short article will show you how to use the Python help() function to view the documentation (Docstring) for a Python module, class, or function. Documenting Your Python Code with Docstrings You can document your Python code with a special string called a docstring. We’ve got a whole article on that here. The short version of it is this: put a triple quoted string immediately after declaring a function, class, or module in Python: “”” Just like this “”” …and you can later read from it using the help() … Read more
