Now that we’ve gotten to the core of what programming languages do, let’s get a little more concrete and see what some of them are and what they look like.

既然我们已经了解了编程语言的核心功能，那么让我们更具体一些，看看其中一些是什么以及它们的外观。

Python (Python)

Python is one of the most pervasive languages right now, due in part to its relative closeness to English and therefore low barrier to entry. It may seem cryptic at first, but you’ll see in time that other languages can get worse.

Python是目前使用最广泛的语言之一，部分原因是它与英语的相对亲近性以及因此较低的进入障碍。乍一看似乎很神秘，但是您会及时发现其他语言会变得更糟。


names = ['Ann', 'Bob', 'Catherine', 'Dave']

print('Hello ' + name)
print('Hello ' + name)

Can you guess what the above will do? First, we create a list of names. We then take each name in the list and “print” it to the screen along with a greeting. It would look something like this:

您能猜出上述内容会做什么吗？首先，我们创建一个名称列表。然后，我们将列表中的每个名称与问候一起“打印”到屏幕上。它看起来像这样：

Neat, huh? (Not all that neat, but hey. We’re learning, people.)

整洁吧？（不是那么整洁，但是嘿。我们正在学习，人们。）

JavaScript (JavaScript)

JavaScript is another very popular language right now due to its use in web browsers like Chrome or Safari. As more and more people use the web, it’s convenient to use a language that works natively on the tools they use. Let’s see the equivalent of the code above, in JavaScript:

由于JavaScript在Chrome或Safari等网络浏览器中的使用，JavaScript现在是另一种非常流行的语言。随着越来越多的人使用网络，使用一种在其使用的工具上本地工作的语言会很方便。让我们看一下与JavaScript中的上述代码等效的代码：


var names = ["Ann", "Bob", "Catherine", "Dave"];

console.log("Hello " + name);console.log("Hello " + name);}
}

You’ll notice there are some differences from Python, but ultimately the program reads similarly. We build a list of names, and then “log” them to the “console” with results identical to the above.

您会注意到与Python有一些区别，但是最终该程序的读取方式类似。我们建立一个名称列表，然后将它们“登录”到“控制台”，其结果与上述相同。

Java (Java)

Java — not at all related to JavaScript — is a programming language used by uncountable pieces of software. It’s the go-to choice when writing enterprise software because of its maturity and portability among operating systems like Windows, Mac OS X, and Linux. Let’s see our program once more, this time in Java:

Java（与JavaScript根本不相关）是无数软件使用的编程语言。由于它在Windows，Mac OS X和Linux等操作系统中的成熟性和可移植性，它是编写企业软件时的首选。让我们再次使用Java来看看我们的程序：

{{System.out.println(“Hello “ + name);System.out.println(“Hello “ + name);}}}}}
}
