I’m pretty new to Python and discovered the nicely presented PEP8 coding style guide linked in the post. Stumbling onto The Hitchhiker’s Guide to Python! has been a very helpful compliment to the official Python Documentaion
Hopefully this post will help others getting familiar with Python.
Thank you for your words of caution. I’ve copied below what the author has to say about Python 2 vs Python 3:
Picking a Python Interpreter (3 vs 2) — The Hitchhiker’s Guide to Python
.
The State of Python (3 & 2)
When choosing a Python interpreter, one looming question is always present: “Should I choose Python 2 or Python 3”? The answer is a bit more subtle than one might think.
The basic gist of the state of things is as follows:
1 - Most production applications today use Python 3.
2 - Python 3 is ready for the production deployment of applications today.
3 - Python 2 reached the end of its life on January 1, 2020 [6].
4 - The brand name “Python” encapsulates both Python 3 and Python 2.
Recommendations
I’ll be blunt:
Use Python 3 for new Python applications. If you’re learning Python for the first time, familiarizing yourself with Python 2.7 will be very useful, but not more useful than learning Python 3. Learn both. They are both “Python”.
So…. 3?
If you’re choosing a Python interpreter to use, I recommend you use the newest Python 3.x, since every version brings new and improved standard library modules, security and bug fixes.
Given such, only use Python 2 if you have a strong reason to, such as a pre-existing code-base, a Python 2 exclusive library, simplicity/familiarity, or, of course, you absolutely love and are inspired by Python 2. No harm in that.
Further Reading
It is possible to write code that works on Python 2.6, 2.7, and Python 3. This ranges from trivial to hard depending upon the kind of software you are writing; if you’re a beginner there are far more important things to worry about.
@ericjmorey Why are you copying part of an article you’ve already linked to? I’m not sure what your point is.
My point is very simple: don’t spend any time on even considering Python 2. The fact the author spent so much time on it shows it’s quite an old guide. (The dates in the git repo confirms this.)
The resource is about exactly this type of information. It’s not a resource that contains code examples. It has concisely presented information about things that aren’t in the Python documentation or is overly technical and verbose in the documentation. It’s a stepping stone providing context to getting more (and more current) resources.
@ericjmorey Except it’s outdated. Here, I’ll write a new paragraph for you: “When you start to learn Python, start with Python 3.10. If you at some point come across an codebase using older versions, you’ll have learned enough to get to grips with the differences outlined in Python documentation.” There, that’s all you need to know.
What is outdated exactly? How has it bee useful to me while still being outdated?
