Sentence Embeddings with Siamese RoBERTa-Networks in Keras

Sentence Embeddings with Siamese RoBERTa-Networks in Keras

If you have ever tried to compare two sentences for similarity, you know that a simple keyword match usually fails. It doesn’t capture the actual meaning behind the words. In my four years of developing Python Keras models, I’ve found that Siamese RoBERTa-networks are the most reliable way to generate deep, meaningful sentence embeddings. Set … Read more >>

Semantic Similarity with BERT in Python Keras

Semantic Similarity with BERT in Keras

Calculating how similar two sentences are goes beyond just matching words. It is about understanding the underlying intent and context of the language used. In my years working with Python and Keras, I have found that BERT is the absolute gold standard for capturing these deep linguistic nuances. Whether you are building a search engine … Read more >>

How to Check if a Directory Exists in Python

Check if a Directory Exists Python

I’ve realized that checking for a directory’s existence is one of those tasks you do almost every day. Whether I am setting up a new logging folder for a financial app in New York or verifying data paths for a California-based startup, I always need a reliable way to handle file systems. In this tutorial, … Read more >>

How to Import Modules from a Parent Directory in Python

Python Import Modules from a Parent Directory

I have frequently run into a common roadblock: trying to access a script located just one level up in the folder hierarchy. It sounds like a simple task, but Python’s default module search path can be a bit stubborn when you are working with complex project structures. In this tutorial, I will show you exactly … Read more >>

How to Pretty Print Dictionary in Python

Pretty Print Dictionary Python

I have spent countless hours staring at messy, unreadable terminal outputs. When you are fetching data from a US Census Bureau API or a complex financial database on Wall Street, a standard print() statement usually returns a wall of text. It is frustrating to debug a nested dictionary that looks like a single, never-ending line … Read more >>

Python Return Statement: How return Works in Functions

Python return statement: Command Prompt output comparing a function that prints with one that returns

The Python return statement ends a function and sends a value back to the line that called it. Write return followed by the value; if you leave the value out, or skip return completely, the caller gets None: I ran each snippet below on Python 3.12.5 from a Windows Command Prompt and pasted the printed … Read more >>

Generate a Random Prime Number in Python [Various Methods]

prime number generator python

Generating a random prime number is a task I’ve encountered frequently over the last decade, especially when building secure backends or working on data encryption. While Python doesn’t have a single “magic button” in the standard library for this, there are several efficient ways to get it done. In this tutorial, I will show you … Read more >>

How to Get the Next Prime Number in Python

find next prime number

Finding prime numbers is a task I find myself doing quite often, especially when working on data encryption or complex mathematical simulations. While it sounds like a simple math problem, doing it efficiently in Python requires a bit of thought, especially as the numbers get larger. In my years of developing backend systems, I’ve had … Read more >>
