Java vs Python: Basic Python for Java Developers

Python is a general-purpose programming language. You can understand its growth in the last couple of years by considering its approachability for learning and its high suitability for data analysis, machine learning, and web development. But what kind of programming language is it? What are some differences when you compare Java vs Python? What can you do with it? And is it really as “easy to learn” as some people claim? You’ll explore Python from a Java perspective in this […]

Creating a better flamegraph visualization

How do you visualize performance data so you can easily spot bottlenecks? Brendan Gregg’s flamegraphs are a great solution, adopted by a large number of profilers and performance tools. However, even great solutions can be improved. With a few small tweaks, you can make flamegraphs much easier to read. To see what I mean, I’ll start with a default flamegraph, and then make it better step by step. Most of the improvements can be achieved by using the right tool […]

Binary, Bytes, and Bitwise Operators in Python

Computers store all kinds of information as a stream of binary digits called bits. Whether you’re working with text, images, or videos, they all boil down to ones and zeros. Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. Python isolates you from the underlying bits with high-level abstractions. You’re more likely to find the overloaded flavors of bitwise operators in practice. But when you work with them in their original form, you’ll […]

Prettify Your Data Structures With Pretty Print in Python

The Python pprint module is helpful in many situations. It comes in handy when making API requests, dealing with JSON files, or handling complicated and nested data. You’ll probably find that using the normal print() function isn’t adequate to efficiently explore your data and debug your application. When you use print() with dictionaries and lists, the output doesn’t contain any newlines. Before you start exploring pprint, you’ll first use urllib to make a request to get some data. You’ll make […]

When you should switch to Python 3.10

Python 3.10 is now available–but should you switch to it immediately? And if not now, when? The short answer after its immediate release was, no, you probably don’t want to switch immediately; quite possibly you can’t switch immediately. Now that some time has passed, we’re getting closer to yes, or at least a maybe. To understand why, we need to consider Python packaging, the software development process, and take a look at the history of past releases. We can then […]

Buying products for your job: estimating value, convincing your boss

You’ve discovered a product that might help you with your job: perhaps a book that will teach you a new and relevant skill, or software that will speed up development. Since you do want to write software better and faster, you are considering buying this product. But, then again, the product costs money, and maybe that money is better spent on something else. So should you buy the product or not? How do you decide? And if it is worth […]

Building a Neural Network & Making Predictions With Python AI

If you’re just starting out in the artificial intelligence (AI) world, then Python is a great language to learn since most of the tools are built using it. Deep learning is a technique used to make predictions using data, and it heavily relies on neural networks. This course will show you how to build a neural network from scratch. In a production setting, you would use a deep learning framework like TensorFlow or PyTorch instead of building your own neural […]
