In Part II, we study Python's built-in core data types, sometimes called object types. Although there are more kinds of objects in Python than we will meet in this part, the types discussed here are generally considered the core data types the main subjects of almost every Python script you're likely to read or write.
This part of the book is organized around major core types, but watch for related topics, such as dynamic typing and general object categories, to also appear along the way. Because chapters in this part lay the groundwork assumed by later chapters, this part will work best if read in a linear fashion.
