About the Book
I suggest this book for everyone who wants to learn Python 3.
My intention is to make this book a useful support for university course students to understand concepts from the classes like CSCI-A 201 or CS 160. I help this understanding with examples from simple to complex.
Until it is finished, you can buy the book for a discounted price. The final book will be around $25.
This book will contain the following topics:
- Differences between Python 2.7 and 3.x
- Python implementations and Installation (Python interpreter, modules with pip)
- Variables and basic types (numbers, strings)
- Basic operators
- Basic string operators
- String formatting
- Date and time
- List comprehension
- Conditions (boolean operators, is, in, not)
- Multiple function arguments
- Partial functions
- Classes and objects
- Code introspection
- Modules and packages
- File I/O
- Exception handling
- Database access
- XML processing
- Website scraping
- Sending mails
- Why not Python 2?
- Why should I care?
- What does “in Anger” mean?
- What will I do exactly?
- Length of the book
- Book structure
- Other publishers
