Python is one of the most widely used programming languages in education, research, and industry. Its clear syntax and readable structure make it especially suitable for beginners who are entering programming for the first time.
As demand for computational literacy continues to grow across disciplines, accessible introductory resources remain essential.
About the book
Non-Programmer’s Tutorial for Python 3 is an introductory guide designed to teach the fundamentals of the Python programming language to readers without prior programming experience. The book is based on earlier tutorial versions and has been adapted specifically for Python 3.
It is intended for complete beginners—particularly individuals who do not identify as programmers but want to understand how programming works. The tutorial progresses gradually, introducing core programming concepts through simple examples and structured lessons.
All example Python source code in the tutorial is granted to the public domain, allowing learners to modify and reuse the code freely.

What you will learn
Readers will gain a foundational understanding of Python programming, including:
- Writing and running basic Python programs
- Using variables and performing simple counting operations
- Making decisions with conditional statements
- Working with loops, including for-loops
- Debugging programs
- Defining and using functions
- Managing lists and dictionaries
- Understanding boolean expressions
- Using modules
- Handling strings
- Performing file input/output operations
