ChrisDefinition Lists: A Python list is an ordered sequence of arbitrary Python objects. It is a mutable object by itself so, unlike Python sets, you can modify a Python list. In this article, you’ll learn everything you need to know on how to create Python lists. Overview — Creating a List in Python There are … Read more
The most Pythonic way to convert a float to a string is to pass the float into the built-in str() function. For example, str(1.23) converts the float 1.23 to the string ‘1.23’. Here’s a minimal example: Python Float to String Precision (Decimals) To set the decimal precision after the comma, you can use the f-string … Read more
What is a LLM? 💡 From a technical standpoint, a large language model (LLM) can be seen as a massive file on a computer, containing billions or even trillions of numerical values, known as parameters. These parameters are fine-tuned through extensive training on diverse datasets, capturing the statistical properties of human language. However, such a … Read more
👨🎓 Source: This first appeared in my free email newsletter. The successive application of very simple computational rules is the underlying mechanism that builds the Universe: “[…] The ultimate machine code of the Universe – yes, it’s computational. Computation isn’t just a possible formalization, it’s the ultimate one.” – Stephen Wolfram The human brain calculates … Read more
💡 Problem Formulation: This article addresses how one can identify odd numbers using the Python programming language. We define an odd number as an integer which is not divisible by 2 without a remainder. For instance, given the input 7, the desired output is a confirmation that 7 is indeed an odd number. Method 1: … Read more
💡 Problem Formulation: Determining the parity of an integer in Python involves checking whether it is divisible by 2 without any remainder. Typically, you might have an integer n and you want to get back a Boolean value, True if n is even, and False if it is not. For example, given n = 4, … Read more
💡 Problem Formulation: When working with text files in a Windows environment, it’s often necessary to perform tasks like creating, reading, appending, and deleting text content programmatically. For example, you might want to create a script that logs events to a text file, or modify configuration files for software deployment. PowerShell, the robust command-line shell … Read more
💡 Problem Formulation: You’re managing multiple servers or systems, possibly in a mixed environment (e.g., some hosts on-premises, others in the cloud), and need to update configuration or text files remotely. The challenge is to do this efficiently and reliably using PowerShell, with a prime example being the need to change a specific line in … Read more
💡 Problem Formulation: Many day-to-day tasks in software development and systems administration involve reading and modifying text within files. Let’s say we have a configuration file where an application’s endpoint URL is written as http://example.com. Now, we need to replace it with https://secure.example.com across multiple files. Efficiently automating this process with a PowerShell script can … Read more
💡 Prompt engineering is a rapidly evolving field within artificial intelligence (AI) and machine learning (ML), focusing on the development of effective prompts that guide AI models, such as large language models (LLMs), to generate desired outputs. 👉 Prompt Engineering: More Prompts Than Atoms in the Universe As AI technologies, particularly generative AI, become more … Read more
💡 Problem Formulation: In Python, you may often need to convert an iterable, such as a list or a tuple, into a set. This is particularly useful when you want to eliminate duplicate elements and unorder the collection. Suppose you have a list [‘apple’, ‘banana’, ‘apple’, ‘orange’] and you want to convert it into a … Read more
💡 Problem Formulation: You may need a list of numbers arranged in descending order. Such a list might be used for counting down, reverse iteration, or to simply organize numerical data in reverse. Let’s say we want to create a list that starts from 10 and ends at 1; the desired output should be [10, … Read more
