Is your program throwing a fit but those error messages are lost somewhere in the avalanche of print statements? Let's fix that! Enter stderr - Python's built-in solution for separating your normal program output from your "everything is on fire" messages. Think of your Python program as having two voices: stdout (its inside voice) and stderr (its "EVERYONE PANIC" voice).

When working with Python, lists are one of the most versatile data structures you’ll come across. It works majorly like Arrays, as seen in other programming languages. The lists allow you to store collections of items, such as integers, strings, or even other lists, and provide numerous ways to access and manipulate the data stored in them.

Many developers focus on developing core application functionalities and pay little or no attention to memory management until they run out of memory, and their apps start crashing, freezing, or experiencing random performance downgrades.

Python is one of the most popular programming languages and choosing the right Integrated Development Environment (IDE) is essential for an efficient workflow. Whether you are a beginner or an experienced developer, choosing the right and best IDE is important because each developer’s needs are unique, whether working on scientific projects, professional applications, or simple scripts. Let’s check out the top 5 best Python IDE as of 2024.

Lambda functions in Python are a powerful way to create small, anonymous functions on the fly. These functions are typically used for short, simple operations where the overhead of a full function definition would be unnecessary. While traditional functions are defined using the def keyword, Lambda functions are defined using the lambda keyword and are directly integrated into lines of code. In particular, they are often used as arguments for built-in functions.

Rounding numbers in Python is an important concept that simplifies calculations and improves the accuracy of results. It helps you adjust numbers by changing them to the nearest whole number or to a specific number of decimal places. Whether you are working with financial data, scientific measurements, or just everyday calculations, rounding ensures that your results are easy to interpret and use.

Have you ever wanted to make sure your assumptions about your code are correct? That’s where assertions come in. In programming, an assertion is a simple way to verify that certain conditions hold true in your code, helping you catch potential errors early before they snowball into bigger problems. Imagine building a house—you wouldn’t start putting up walls without first making sure the foundation is solid, right? Assertions work the same way in your code.

Python is a powerful and versatile programming language. However, like any language, it comes with its own set of challenges. One common issue developers encounter is the KeyError exception. In this tutorial, we’ll delve into what a KeyError is, explore common scenarios where it occurs, and provide practical solutions and best practices to handle and prevent this error.

This is the first of a two-part series using Django, htmx, and Stripe to create a one-product e-commerce website. In this part, we'll start our Django project and integrate it with htmx. In the second part, we'll handle the orders with Stripe. Let's get going!

Logging is a crucial practice that helps developers monitor, debug, and maintain their applications. Python, a versatile and widely used programming language, provides a comprehensive logging module that makes it easy to integrate logging into your applications. This post introduces Python logging, covering the basics, various logging levels, practical implementations, and more.
