No - this is common for folks who move to Python from other C-like languages. I believe what you are looking for is ways to make your code more <a href="http://shalabh.infogami.com/Be_Pythonic2" rel="nofollow noreferrer">"Pythonic"</a>. The good news is the more Python you write the more Pythonic your code will become. It is a natural overflow of the "how can I do this more simply" attitude.

Another good place to look at is <a href="http://www.python.org/dev/peps/pep-0020/" rel="nofollow noreferrer">The Zen of Python</a>. These attitudes towards Python development will also help you in the same regard.

How many Python idioms can you find in that?

blocks|key|1623174|text|为了补充Andrew+Hare和Baishampayan+Ghose的答案...|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1623175|要学习任何语言的习惯用法，必须阅读用该习惯用法编写的代码。我仍然在学习Python成语，但我已经用其他语言经历过这一点。我可以读到关于列表理解的文章，但只有当你看到这些东西在使用时，你才会真正明白，“哇！太棒了！两行代码，它就像水晶一样清晰！”所以去找一些你感兴趣的pythonic代码，并开始阅读和理解它。如果你在一个工作程序的背景下看到一切，这些知识会更好地留在你的脑海中。|1623176|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

To add to the answers of Andrew Hare and Baishampayan Ghose...

To learn the idiom of any language must involve reading code written in that idiom. I'm still learning the Python idiom, but I've been through this with other languages. I can read about list comprehensions, but the lightbulb only really comes on when you see such things in use and say, "Wow! That's awesome! Two lines of code and it's crystal clear!" So go find some pythonic code that you find interesting and start reading it and understanding it. The knowledge will stay in your head better if you see everything in the context of a working program.

Write some Python code and post it on SO for review and feedback whether it is pythonic.

Apart from stuffs like Generators, Iterators, List Comprehensions etc mentioned by other folks here, I would like to suggest couple of more concepts which I feel definitely adds value to someone attempting to do things the 'pythonic' way. These are Decorators and Meta Classes.

For Decorators, <a href="https://stackoverflow.com/a/1594484/1005500">this</a> stackoverflow answer is highly recommended and for Meta Classes you can go through <a href="https://stackoverflow.com/a/6581949/1005500">this</a>.

blocks|key|1623427|text|我建议找一位私人的python专家。向他们展示你的一些代码，并让他们复查/重写成惯用的python。这样你就会开悟了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1623428|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I would suggest finding a personal python guru. Show them some of your code and have them review/rewrite it into idiomatic python. Thus will you be enlightened.

To echo TLHOLADAY, read the standard library. That's where the "pythonic" stuff is. If you're not getting a good feel there, then read the source for sqlachemy or django or your project of choice.

I'm in the process of learning Python while implementing build scripts and such. And for the moment everything is working fine in that the scripts do what they need to do. But I keep having the feeling I'm missing something, such as "The Python Way". I know build scripts and glue scripts are not really the most exciting development work and may hardly be a candidate for revealing the true power of Python but I'd still like the opportunity to have my mind blown. I develop mostly in C# and I find that my Python code looks awfully similar in structure and style to a lot of my C# code. In other words I feel like I'm thinking in C# but writing in Python.

Am I really missing something?

(Note: I realize this isn't so much a programming question and it's quite broad and there may not be a definitive answer so mod me down into oblivion if you have to.)

Python: Am I missing something?

Python

我正在学习Python，同时实现构建脚本之类的东西。就目前而言，一切都很好，因为脚本做了他们需要做的事情。但是我一直觉得我错过了一些东西，比如“Python的方式”。我知道构建脚本和粘合脚本并不是真正令人兴奋的开发工作，可能很难成为展示Python真正力量的候选者，但我仍然希望有机会让我大吃一惊。我主要使用C#进行开发，我发现我的Python代码在结构和风格上与我的许多C#代码非常相似。换句话说，
