什么是Python，你想知道吗？嗯，这是一个很好的问题，特别是对于那些完全不熟悉这个问题的人。你看，Python是一种高级编程语言，它包含主要用于应用程序和 Web 开发的集成动态语义。
什么是 Python 编程语言
当谈到快速应用程序开发(Rapid Application Development)时，我们不得不说Python在这方面是最好的，因为它提供了动态绑定和动态类型选项。
应该注意的是，大多数程序员会说Python学习起来非常简单。这样做的原因是因为它只需要一种特殊的语法，它更注重可读性而不是其他任何东西。此外，众所周知，开发人员能够比其他语言更容易地阅读和翻译用Python编写的代码。(Python)
现在，由于更容易阅读和翻译，该语言的维护和开发成本变得更低。此外(Furthermore)，与他人合作不应该是一个大问题，因为在语言和经验上没有明显的障碍。
Python的有趣之处在于它的支持或包和模块，这是许多Python程序员赖以生存的特性。对模块和包的支持意味着程序员可以以模块化的方式设计他们的程序。代码可以通过简单地缩放以适应多个项目来重复使用。
不仅如此，还可以相对轻松地导入和导出模块，这总是一件好事。
使用Python(Python)有很多好处，但我们更喜欢免费提供解释器和标准库的好处。但这还不是全部；你看，Python并不是单一平台独有的，因为它在所有主要平台上都可用，包括Windows、Mac和Linux之类的平台。

1]我们如何使用Python？
好的，所以关于Python的最好的事情之一就是它是一种通用编程语言。是的，我们的意思是它几乎可以在所有情况下，如果(All Trades)你愿意的话，它是万事通。(Jack)此外，我们应该指出Python是一种解释型语言，这意味着代码不会在运行时被翻译成计算机可读的格式，而是在运行之后。
此外，该语言实际上被视为“脚本语言”，因为它最初是为琐碎的项目设计的。但显然，情况已不再如此，因此，该语言已成为编程世界中最受欢迎的语言之一。
2] 谁更有可能使用Python？
永远不应低估这种语言的多用途方面。如果您看一下NASA，您可能没有意识到Python在(Python)航天(Space)工业中非常流行。它是为国际(International) 空间站(Space)的Robonaut 2提供动力的中央指挥系统。
在视频游戏(Video Games)的世界中，该语言也很流行。我们了解动视(Activision)使用它来构建和测试其标题。不仅如此，它还用于跟踪作弊者并阻止他们。
人工智能是Python快速(Python)增长(Intelligence)的另一大难题。与Java(Java)和许多其他语言相比，占用空间小且易于使用使其非常适合该领域。

初学者的示例代码
1]世界你好！
根据传统，第一次学习编码的人应该首先编写Hello World，这就是我们要做的。
首先，打开Python，然后键入以下代码行，然后按键盘上的Enter键：
print(‘Hello World!’)
最终结果应如下图所示。
让我们看一些更高级的东西，我们将在其中创建字典。你看， Python(Python)中的字典是无序的、可变的和索引的。此外，字典有键值，它们是用大括号写的。
2]创建打印字典
现在是时候创建一个简单的打印字典了：
thisdict = {
"brand": "Subaru",
"model": "Impreza",
"year": 2017
}
print(thisdict)
You can easily change the values of a specific item by running this code. Note that we’ve referred to the key name:
thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
thisdict["year"] = 2020
结论
如果您对编程很认真，那么我们强烈建议您学习Python，因为由于人工智能和机器学习的兴起，它的使用在未来会进一步增加，Python已经在这个领域蓬勃发展。

What is Python programming language?
What is Python, you wonder? Well, that’s a good question, especially for those who are completely new to this. You see, Python is a high-level programming language that comes packed with integrated dynamic semantics designed mainly for app and web development.
What is Python programming language
When it comes down to Rapid Application Development, we have to say that Python is best in this regard because it offers dynamic binding and dynamic typing options.
One should note that most programmers will say Python is very simple to learn. The reason for this is because it requires just a special syntax that focuses much on readability than anything else. Furthermore, it is well known that developers are capable of reading and translating code written in Python much easier than other languages.
Now, because of the easier reading and translating, the language becomes cheaper to maintain and develop. Furthermore, collaborating with others shouldn’t be a huge problem since there is no significant barrier to language and experience.
What’s interesting about Python is its support or packages and modules, and that is a feature many Python programmers have come to live by. The support for modules and packages means programmers can design their programs in a modular style. Codes can be reused across multiple projects by simply scaling them to fit accordingly.
Not only that, but it is also possible to import and export modules with relative ease, and that is always a good thing.
There are multiple benefits of using Python, but we prefer the one where the interpreter and the standard library are all available free of cost. But that’s not all; you see, Python is not exclusive to a single platform because it is available on all the major ones, which includes the likes of Windows, Mac, and Linux.

1] How do we use Python?
OK, so one of the best things about Python is the fact that it is a general-purpose programming language. Yes, we do mean that it can in almost all situations, a Jack of All Trades if you will. Additionally, we should point out that Python is an interpreted language, and that means, the code is not translated to a readable format for computers at runtime, but rather, after.
Furthermore, the language, in truth, is viewed as a “scripting language” because it was originally designed for trifling projects. But clearly, that is no longer the case, and as such, the language has become one of the most loved in the world of programming.
2] Who is more likely to use Python?
The multipurpose aspect of this language should never be underestimated. If you take a look at NASA, you might not have realized that Python is quite popular in the Space industry. It is the central commanding system that powers the International Space Station’s Robonaut 2.
In the world of Video Games, the language is quite popular as well. We understand that Activision uses it to build and test its titles. Not only that, but it is also used to track cheaters and stop them in their tracks.
Artificial Intelligence is another big piece of the puzzle where Python is growing quite rapidly. The small footprint and ease of use make it perfect for this area when compared to the likes of Java and many others.

Sample codes for beginners
1] Hello World!
According to tradition, folks who are learning to code for the first time should program Hello World before all else, so that’s what we’re going to do.
To begin, open Python, then type the following line of code, and follow up by hitting the Enter key on your keyboard:
print(‘Hello World!’)
The end result should look like the figure below.
Let’s look at something more advanced where we will be creating a dictionary. You see, a dictionary in Python is unordered, changeable, and indexed. Furthermore, the dictionaries have key values, and they are written using the curly bracket.
2] Create a print dictionary
It’s now time to create a simple print dictionary:
thisdict = {
"brand": "Subaru",
"model": "Impreza",
"year": 2017
}
print(thisdict)
You can easily change the values of a specific item by running this code. Note that we’ve referred to the key name:
thisdict = {
"brand": "Ford",
"model": "Mustang",
"year": 1964
}
thisdict["year"] = 2020
Conclusion
If you are serious about programming, then we urge you to learn Python because its usage will increase even further in the future due to the rise of artificial intelligence and machine learning, a space where Python is already thriving quite comfortably.
