https://100days.cyberako.blog/ Daily notes from my #100DaysOfCode challenge, following the Talk Python course. en https://100days.cyberako.blog/days/000/ https://100days.cyberako.blog/days/000/ Fri, 23 Oct 2026 12:00:00 +0000 <p>Tomorrow I start the #100DaysOfCode challenge with Python, working through Talk Python's <em>#100DaysOfCode in Python</em> course and writing up each day here.</p> <h2>The plan</h2> <ul> <li>Code every day for 100 days</li> <li>Follow the course's 33 three-day modules, from datetimes and collections through to Flask, databases and GUIs</li> <li>Post a short write-up here each day: what I did, what I learned, and the code</li> </ul> <h2>What the course covers</h2> <p>The course is taught by Michael Kennedy, Bob Belderbos and Julian Sequeira. The opening "sampling of what we'll cover" lecture gives a taste of the ground it covers:</p> <ul> <li><strong>Python fundamentals:</strong> collections, lists and dictionaries</li> <li><strong>Reliable code:</strong> testing with pytest, proper error handling, and logging to keep a history of what an app has done</li> <li><strong>Object-oriented programming:</strong> building a Dungeons and Dragons style game with classes and inheritance</li> <li><strong>Data from the outside world:</strong> JSON, calling JSON-based web services, web scraping (turning any HTML page into a data source) and RSS feeds</li> <li><strong>Automating services:</strong> the Twitter and GitHub APIs, and sending email</li> <li><strong>Automating the desktop and web:</strong> programming against Excel, and driving a browser with Selenium to log in, navigate and click buttons</li> <li><strong>Web apps and databases:</strong> Flask (probably the easiest way to write a web app in Python), the built-in SQLite database, and the SQLAlchemy ORM for mapping classes to database tables</li> <li><strong>Data visualisation:</strong> graphs with Plotly, with about a quarter of the course presented in Jupyter notebooks</li> <li><strong>GUIs:</strong> cross-platform desktop apps for Windows, Linux and macOS in just a few lines of code</li> <li><strong>Building APIs:</strong> extending Flask to create my own API and put it on the internet</li> </ul> <p>That's only part of it. There are 33 modules in all, three days each.</p> <p>Flask is the one I've already had a head start on, because this blog is a Flask app. Each post is written in Markdown, and Frozen-Flask turns the site into static pages hosted on AWS.</p> <p>The grid on the home page fills in as each day gets logged.</p>
