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
- Tuples
- Lists
- Dictionaries
- Sets
- Generators
- List comprehension
- Conditions (boolean operators, is, in, not)
- Loops
- Functions
- Multiple function arguments
- Partial functions
- Decorators
- Classes and objects
- Code introspection
- Modules and packages
- File I/O
- Exception handling
- Database access
- Networking
- Parallelism
- XML processing
- Website scraping
- Sending mails

Open Sourcing Mental Illness is a non-profit, 501c3 corporation dedicated to raising awareness, educating, and providing resources to support mental wellness in the tech and open source communities.
OSMI began in 2013 as a speaking campaign by Ed Finkler. Ed started speaking at tech conferences about his personal experiences as a web developer and open source advocate with a mental health disorder. The response was overwhelming, and Ed has continued to speak, gather data, and organize efforts to change experiences of those with mental health disorders in the tech workplace. This includes speaking at conferences and companies, conducting research, and creating documentation to assist companies in making supportive environments for those impacted by mental health disorders. He is assisted in these efforts by selfless volunteers who bring their time and expertise to bear on this important issue.
