Planning to write a book about Web Scraping in Python. Click here to give your feedback I have been covering web scraping for a long time on this blog for a long time but they were mostly in Python; be it requests, Selenium or Scrapy framework, all were based on Python language but scraping is not limited to a specific language. Any language that provides APIs or libraries for an Http client and HTML parser is able to provide you web scrapi....

Unicode support in my experience seems to be one of those hand wavy things where most people respond to the question of “Do you support unicode?” with Yeah we support emojis, so yes we support unicode! 😃😭😈 Which is partially correct… It’s certainly a good start. However unicode is more than emojis. So lets take a step back. What is unicode? It’s actually easy to explain, here it is taken from the wiki page “A standard for represen..

DBCore can now generate a TypeScript/React CRUD UI that is automatically hooked up to the generated REST API (in Go). The UI has full support for login, viewing (and filtering), editing, and creating database entities. PostgreSQL, SQLite and MySQL are supported. How to use? The goal of this project is primarily to provide as much useful boilerplate as possible for full-stack applications. The system is probably not sufficient to be an....

Introduction Link to heading This post is about a project to generate wav files with a neural network. These are files with the audio in the waveform domain, i.e. as sound samples such as that which might be converted to mp3 files. I had hoped to be able to generate some form of music, but both training and generation are proving too processor intensive at the moment, so I’m going to write up what I have for the time being and p..

I have wanted a 3D printer for a very long time. I hope you can tell from my ACM Queue column that I like to do a lot of research and I tend to want the best thing. I had been keeping my eyes on the 3D printer product space for quite some time. This article is going to go over the technical details behind 3D printing as well as my experience with two different products. When I finally decided to buy a 3D printer, I wanted to try ones th....

Have you wanted to work with PDF files in Python? Maybe you want to extract text, merge and concatenate files, or even create PDFs from scratch. Are you interested in building hardware projects using a Raspberry Pi? This week on the show we have David Amos from the Real Python team to discuss his recent article on working with PDFs. David also brings a few other articles from the wider Python community for us to discuss.

I have an interesting technical situation facing me: A docker container which runs persistently and writes JSON files to a directory Each JSON file contains short form messages with JSON encoding along a variety of metadata fields Each file is idempotent i.e. once it exists in the directory will never be written to again Each file is named for a timestamp Each file needs to: Have ridiculous, non-JSON comments removed from the beginnin....

I’ve started this website with the Beautiful Hugo theme. At that point in time I was learning how Hugo works. I knew I wanted to design my own theme, only because I like customizing and designing. The theme I’m currently using was designed and written by me. I’m not a web developer so it’s not professional quality. It’s made by me - that’s what matters. I’ve never implemented a comments system in my own theme. That has recently changed!..

When developing REST API projects or CLI Applications with Node.js, it is very common to use the open source npm dependency package manager to include frameworks and tools in these projects. To a certain extent, this is beneficial as it can help us reduce development time. Including stable packages that are well tested and maintained by the community, serves certain needs for our project. However, it can also turn against us and be a proble..

I recently had to look at a complex JSON structure in Python. The way that I wanted to do this was to look at a sorted list of the keys. Here's the core of what I came up with: keys = my_json . keys () keys = list ( keys ) keys . sort () I keep a common_json.py library and this is what I came up that I can call from: common_json . print_sorted_keys ( json_dict ) Note : If you are debugging insi....
