This week's book giveaways are in the Jython/Python and Object-Oriented programming forums. We're giving away four copies each of Machine Learning for Business: Using Amazon SageMaker and Jupyter and Object Design Style Guide and have the authors on-line! See this thread and this one for details.
With all due respect, if you're a beginner, are you sure you're ready for advanced stuff? What kind of level and content are you looking for? Note that advanced books generally are not free, so if you're not satisfied with what you found already, you're most likely out of luck.
