Last week's code challenge focused on building a Hacktoberfest progress checker using the Bottle framework, and it saw diverse submissions from participants. Martin, known as clamytoe, developed a simple script on his iPhone using Pythonista, while kiniadit created a feature-rich script, hkfst.py, offering anonymous API access and local server setup to track Hacktoberfest progress for a single user. Pweids submitted a minimalist version, emphasizing simplicity over complexity, and bbelderbos crafted a solution using Bottle and the GitHub API, with plans to incorporate pytests for further testing. Participants were encouraged to complete Hacktoberfest for a chance to receive a free T-shirt from DigitalOcean, and the community spirit was bolstered with a reminder to continue coding in Python.
