Do you need to transfer an extensive data collection for a science project? What&rsquo;s the best way to send executable code over the wire for distributed processing? What are the different ways to serialize data in Python? Christopher Trudeau is back on the show this week, bringing another batch of PyCoder&rsquo;s Weekly articles and projects.
Christopher shares a tutorial by Real Python author Bartosz Zaczyński called &ldquo;Serialize Your Data With Python.&rdquo; This comprehensive guide moves beyond XML and JSON to explore multiple data formats and their potential use cases. It&rsquo;s a deep dive into the topic and provides a thorough resource for future reference.
We also discuss a Real Python tutorial about naming conventions in Python that use single and double underscores. The piece covers differentiating between public and non-public names in APIs, writing safe classes for subclassing purposes, and avoiding name clashes with keywords.
We also share several other articles and projects from the Python community, including a couple of release announcements and news items, a discussion about never being taught how to construct quality software, building a small REPL in Python, using the <code>key</code> parameter in Python functions and methods, a framework for RESTful APIs using Flask and SQLAlchemy, and a Rust-based HTML sanitizer for your Python projects.
