I would be interested in knowing what the StackOverflow community thinks are the important language features (idioms) of Python. Features that would define a programmer as Pythonic.
Python (pythonic) idiom - "code expression" that is natural or characteristic to the language Python.
Plus, Which idioms should all Python programmers learn early on?
Thanks in advance

Idiomatic Python is what you write when the only thing you're struggling with is the right way to solve your problem, and you're not struggling with the programming language or some weird library error or a nasty data retrieval issue or something else extraneous to your real problem.
Python is written in C (actually the default implementation is called CPython).
The python language is one of the most accessible programming languages available because it has simplified syntax and not complicated, which gives more emphasis on natural language. Due to its ease of learning and usage, python codes can be easily written and executed much faster than other programming languages.
In short, “pythonic” describes a coding style that leverages Python's unique features to write code that is readable and beautiful.
Python is a language that can be described as:
"rules you can fit in the palm of your hand with a huge bag of hooks".
Nearly everything in python follows the same simple standards. Everything is accessible, changeable, and tweakable. There are very few language level elements.
Take for example, the len(data) builtin function. len(data)
works by simply checking for a data.__len__()
method, and then calls it and returns the value. That way, len()
can work on any object that implements a __len__()
method.
Start by learning about the types and basic syntax:
Then move on to learning about how python works:
dir()
function__builtins__
Once you have an understanding of how to fit pieces together, go back and cover some of the more advanced language features:
__len__
(there are tons of these)And once you have a comfort level with these items (with a focus on what makes them pythonic), look at more specific items:
And never forget The Zen of Python (by Tim Peters)
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!
