Python is a remarkably powerful dynamic programming language used in a wide variety of situations such as Web, database access, desktop GUIs, game and software development, and network programming. Fans of Python use the phrase "batteries included" to describe the standard library, which covers everything from asynchronous processing to zip files. The language itself is a flexible powerhouse that can handle practically any application domain.
This task-based tutorial on Python is for those new to the language and walks you through the fundamentals. You'll learn about arithmetic, strings, and variables; writing programs; flow of control, functions; strings; data structures; input and output; and exception handling. At the end of the book, a special section walks you through a longer, realistic application, tying the concepts of the book together.

Double back-quotes indicate code font, e.g. ``ValueError``.
Single *s represent italics, e.g. *raises*.
there is a missing single quote after child fare. It should be rewritten as follows:
Paragraph beginning "The find function ..." mixes up find and index. It should be re-written as follows:
The ``index`` function *raises* a ``ValueError``; this is an example of an exception, which we will talk about in more detail in Chapter 9. The ``find`` function returns -1 if the string being searched for is not found.
Replace "html = resp.read()" with "html = page.read()"
In the code inside the "print" function, replace "Person('%s', age)" with "Person('%s', %s)".
