Download : LiveLessons – Python Fundamentals


Author: Wesley J Chun
Released: Dec 23, 2008 | Duration: 8h 5m 49s

In this one-of-a-kind video package, leading Python developer and trainer Wesley Chun helps you learn Python quickly and comprehensively, so that you can immediately succeed with any Python project.

Just click and watch: One step at a time, you will master Python fundamentals. If you already have Python experience, these videos will help further develop your skills. The lessons start with an introduction to the core features of the Python language, including syntax basics and standard types and operations. The lessons progress into advanced topics, such as Python’s memory model and object-oriented programming.

This LiveLessons video course closely mirrors the topics covered in its sister publication, Core Python Programming, Second Edition (Prentice Hall, 2007). As in the book, viewers will find review questions and coding exercises at the end of each lesson in the video booklet to test the material introduced in the video and printed parts of the lesson.

Lesson 1: Introduction
The first lesson helps viewers set up and ready to learn Python. Material covered includes installation, how/where to write Python source code, development environment, Python’s interactive interpreter, etc., all of which culminates in the classic “Hello World!” example. 
Lesson 2: Getting Started
Before diving straight into Python, it’s important to learn where Python has come from and where it is going. This lesson features a brief language backgrounder, what it’s key advantages are, and most importantly, goes into some detail about Python’s current transition to its next generation release, Python 3. The lesson concludes with both the expected “Hello World!” example as well as a demo of the core language fundamentals that are covered in the remainder of this LiveLessons video course. 
Lesson 3: Python Syntax Basics
True to its name, this lesson covers the basic language syntax rules: code structure, statements, delimitation, variables, assignment, plus rules and guidelines for identifier names. Of course, those are language independent aspects, but the latter part of the lesson focuses on Python-specifics such as keywords and built-in functions. It then concludes with three very important introductions: how to create and call functions, how to import functionality from other Python modules, and the raw_input() built-in function which can be used to obtain user input from the command-line. 
Lesson 4: Standard Types
The longest lesson in this LiveLessons video course features an in-depth look into Python’s standard data types. It starts off with light fare such as Boolean values and the various operators and built-in functions that work with most Python types. This is followed by a comprehensive look at Python’s numeric, sequence, and hashing types, as well as the operators and built-in functions and methods that apply to each of those types. 
Lesson 5: Objects and Memory Model
This is the first lesson of our LiveLessons video course that you can skip and come back to later. It goes into detail about Python’s memory model and is strongly recommended viewing but may be too advanced for those who are just learning Python. Topics covered in this lesson include objects, references, and memory management. It also features a way of categorizing each of the standard types using various models to help you learn and understand them much better; then concludes several quizzes to test your comprehension. 
Lesson 6: Loops and Conditionals
It’s back to the basics with this lesson, covering generic flow control using loops and conditionals. The lesson begins with a review of Python’s syntax rules then covers Python’s if statement then its for and while loops as well as auxiliary constructs, statements, and built-in functions. 
Lesson 7: Files and Input/Output
In this lesson, we review what files — including the standard files — are and provide the context in which to think about files in Python. Material covered in this lesson includes the open() built-in function as well as file object methods; it then concludes with a brief discussion of other forms of persistent storage available for Python users. 
Lesson 8: Errors and Exceptions
Run-time exception handling may still seem “new” even though the concept has been around for a long time, but it is pretty much of a requirement of most modern-day programming languages. This lesson begins with a review of exceptions then discusses how to accomplish exception handling in Python. The latter part of the lesson covers other exception-related functionality featuring the else, finally, raise, and assert statements as well as how to create (and use) exception classes. The lesson concludes with what you CANNOT do with exceptions as well as a reminder that not all exceptions mean some error is involved… they can be just warnings or simple notification of loop termination. 
Lesson 9: Functions and Functional Programming
Creating and calling functions were briefly introduced back in an earlier lesson, so the goal of this lesson is to fill in more of the gaps as well as introducing other features of functions and functional programming found in Python. In particular, a good amount of time is spent on features that focus on functions arguments/parameters, i.e., keyword arguments, default values, return values, calling convention applicability in Python, etc. The remainder of the lesson covers variable scope, namespaces, functional programmings, anonymous functions, variable arguments, and finally, argument grouping. 
Lesson 10: Object-Oriented Programming
The final lesson can also be deferred by the viewer. Although Python is an object-oriented programming language, using OOP is not required to create a working application. Users can learn and use OOP when they are ready. This lesson is fairly comprehensive, starting with a general introduction to OOP then gradually bringing Python into the picture. The remainder of the lesson covers all the core OOP components of Python: classes, class attributes, instances, instance attributes, methods, subclasses and finally, multiple inheritance.
