Machine Learning: Random Forest with Python from Scratch - Tuples

The video tutorial covers string operations such as finding the starting index of a substring and converting strings to uppercase. It then introduces tuples as immutable Python objects, explaining their characteristics and how they differ from arrays. The tutorial includes practical exercises on creating and accessing tuples, highlighting their immutability. The video concludes with an assignment to explore tuple documentation and implement a method.
