This book is not for a completely noob programmer, it expects some initial programming experience.
It's an easy to understand introduction to the Python programming language which focuses on teaching concepts via examples. The initial chapters explain various concepts and in a later chapter, you will build a command line todo list manager.
The motto of this book is not just teach the language, but to enable you to write tools which you would use in day to day life, like a simple todo list manager, we encourage you to explore the language more after you read the book and start writing tools for your daily usage.
There are a large number of languages out there and new ones coming out every week, thus, it begs the question why learn Python over X.
Python has the following advantages:
- 1.Easy to understand syntax. Reads just like English.
- 2.Huge community.
- 3.Open source hence millions of packages available.
- 4.Short time needed for writing code.
A programming language's usability is direct proportion to the size of its community squared, this is because the core team writes the language, but the content(books, podcasts, tutorials, packages, Q&A) surrounding the language is created by the community.
This guide focuses only on Python3, Python2 is on life support and we do not recommend using it, unless there is an exceptional scenario.
We have thirteen chapters:
- Each chapter or topic has an associated YouTube screencast.
- Each chapter has concepts explained by an example (can be as stupid as 1+1=2)
- Code that is supposed to run on the Interpreter starts with
>>> not True.>>> not TrueFalseIn this case,
>>> not Trueis the statement and
Falseis the output.
- Code that doesn't start with
>>>is supposed to be run in a file with the extension .py
- If there is significant code for the chapter, you can find a file in the code repository, please look on the basis of chapters.
- Read the chapters end to end.
- Watch the YouTube screencast, there is a reason why they are free!
- Do NOT search the Internet for things like "how to do X in python", use the documentation.
- 1.Linux and Mac: Use a package manager to install the python3 package.
- 4.iOS: Python3 for iOS (not free).
This tutorial is the culmination of the various Python trainings I have given in the past. There was a lack of a guide which taught programming by building tools without overwhelming the readers, thus, this project got started.
They say that write the book you wish existed in the world. This is a book which I wished existed when I was learning the language.
Please note that I don't profess to be a God at anything, but I do feel that good things happen when a group comes together for one goal.
This is an open source guide and I invite you to contribute.
We need your help to become a great guide! All contributions are welcome. Please raise an issue on Github!
