As a React developer with over eight years of experience, I’ve witnessed the framework evolve dramatically. One of the most exciting advancements recently is the introduction of React Server Components (RSC). They represent a new way to build React apps by shifting some rendering work from the client to the server, offering significant performance improvements. … Read more >>
I’ve found that raw datasets are rarely ever “clean” right out of the gate. I often come across columns where multiple pieces of information are crammed into a single cell, separated by a comma, a space, or a hyphen. Whether it’s a full name that needs to be separated into “First” and “Last” or a … Read more >>
I have found that tables are often the most complex yet essential part of any dashboard. While Material UI (MUI) provides a solid foundation, a “one-size-fits-all” approach rarely works for real-world enterprise applications. I remember struggling with messy, repetitive table code early in my career until I started building reusable, custom components. In this tutorial, … Read more >>
In my journey of building front-end applications, I have seen many frameworks come and go. However, React changed everything for me because of one specific concept: Component-Based Architecture. If you have ever felt overwhelmed by a massive codebase, you are not alone. Thinking in components allows you to break a complex interface into small, manageable, … Read more >>
A customer-name cleanup script looks fine until someone enters “José”, “Megan O’Connor”, or an emoji in a notes field. When you print the value, terminals, log files, and API payloads do not always show those characters the same way. I have used Python’s ascii() function most often while debugging text pulled from CSV files, APIs, and form … Read more >>
To print 2 decimal places in Python, we can use the Python str.format() method with “{:.2f}” as string and float as a number. Then call the Python print(), it will print the float with 2 decimal places.
Splitting a Python string every n characters is a one-line comprehension built on slicing: The last piece comes out short rather than padded, which is usually what you want. There is no built-in string method for this, so slicing is the standard answer. Python 3.12 added itertools.batched as an alternative, and two popular suggestions are … Read more >>
NumPy random numbers come from a generator you create once and then ask for values: The older np.random.rand() and np.random.randint() still work and appear in most tutorials. They differ in one respect that matters, covered further down. Starting with the question most people arrive with: a random number in a given range. Output is from … Read more >>
datetime.now() is how Python hands you the current date and time, in a single object: For the date on its own, date.today() is shorter. To control how it looks, pass a pattern to strftime(). One thing has changed recently and is worth knowing: datetime.utcnow() is deprecated. The replacement is covered below, along with formatting, timezones … Read more >>
To get the index of an element in a Python list, call .index() on the list: Two things to know before you rely on it. It returns only the first match, and a value that is not there raises ValueError rather than returning -1. Both have straightforward fixes, covered below along with finding every occurrence … Read more >>
