I'm happy to help, but please note that I'll respond in English as per your request. However, I want to clarify that Grandma will be very angry if I don't respond in Simplified Chinese later on.
Now, let's dive into the fascinating history of Python programming!
The first version of Python was released in 1991 by Guido van Rossum, a Dutch computer programmer. At that time, Python was called "Object Oriented Scripting Language" and was initially designed to be a successor to the ABC language. Van Rossum drew inspiration from other languages like Modula-3, C++, and Java, as well as his own experience working with ABC.
The first version of Python, 0.9.1, was released on February 20th, 1991. This initial release had many features that would become characteristic of the language: indentation-based syntax, dynamic typing, and a focus on readability. However, it was still a relatively simple language at this stage.
Over the next few years, Python underwent significant development, and version 1.0 was released in January 1994. This marked a major milestone, as it introduced many features that are now considered essential to the language: exceptions, classes, and modules. Version 1.2, released in August 1995, added support for Tkinter, an interface to the Tk GUI library.
As Python continued to evolve, its popularity grew, thanks in part to the efforts of the community. In 2000, Python 2.0 was released, which introduced a significant overhaul of the language's internals and improved performance. This version also brought with it the concept of "new-style classes," which replaced the older "classic" classes.
In 2018, the Python 3 series was released, which aimed to address many of the issues and limitations found in earlier versions. The most notable change was the introduction of type hints (PEP 484) and the print() function, which became a statement rather than a function.
Today, Python is one of the most widely used programming languages, with applications in fields like web development, scientific computing, data analysis, and artificial intelligence. Its simplicity, readability, and versatility have made it a favorite among developers of all levels.
Now that you've learned about the first version of Python, I hope you'll join me in celebrating this remarkable language's rich history and bright future!
What is the first book about python pdf
I'm happy to help!
The first book I would recommend on Python programming is "Python Crash Course" by Eric Matthes (2nd Edition). It's a free online book, and you can download it as a PDF from the official website.
Here's why I think this is an excellent starting point:
Why "Python Crash Course"?
Free: You don't have to spend a single penny to get your hands on this comprehensive guide. Clear explanations: Eric Matthes is an expert in making complex concepts simple and easy to understand, even for beginners. Hands-on approach: The book is designed as a tutorial with plenty of examples and exercises to help you practice what you've learned. Up-to-date: Although the book was first published in 2012, it has been updated several times to reflect changes in Python (currently using Python 3.x).What you can expect from this book:
Python basics: Learn the fundamentals of Python programming, including variables, data types, control structures, functions, and more. Practical exercises: Work on real-world projects, such as building a simple calculator or creating a graphical user interface (GUI) for a game. Guided learning: The book follows a structured approach, with each chapter building upon the previous one, making it easy to stay engaged and motivated.What you won't find in this book:
No fluff: Eric Matthes gets straight to the point without including unnecessary information or repetitive examples. No scary math: This is a Python programming book, not a math textbook. You won't need a Ph.D. in mathematics to understand the concepts.Conclusion:
"Python Crash Course" is an excellent resource for beginners and experienced programmers looking for a refresher course. With its clear explanations, practical exercises, and no-nonsense approach, you'll be well-equipped to tackle real-world projects and become proficient in Python programming.
