PyBites conducted a weekly code challenge that involved predicting when the Python Package Index (PyPI) would reach 100,000 packages. Participants explored two main approaches: using PyPI’s RSS feed to calculate a moving average of package additions and using archived data from the Wayback Machine, applying scipy's UnivariateSpline for extrapolation. Initial predictions suggested the milestone would be reached by the 1st of March, but the actual date turned out to be the 4th of March, with the winning solution featuring Bokeh visualizations. PyBites celebrated the milestone on social media, marking a significant achievement for the Python community. Participants were encouraged to provide feedback and suggest future challenges, with plans to explore sentiment analysis using the Twitter API in the upcoming week.
