首先，我们普及一下编程语言的基础知识。用任何编程语言来开发程序，
都是为了让计算机干活，比如下载一个 MP3，编写一个文档等等，而计
算机干活的 CPU 只认识机器指令，所以，尽管不同的编程语言差异极
大，后都得“翻译”成 CPU 可以执行的机器指令。而不同的编程语言，
干同一个活，编写的代码量，差距也很大。
比如，完成同一个任务，C 语言要写 1000 行代码，Java 只需要写 100
行，而 Python 可能只要 20 行。
所以 Python 是一种相当高级的语言。(First, let's popularize the basics of programming languages. Develop programs in any programming language.
Is to make the computer work, such as download a MP3, write a document, and meter
Computers work with CPUs that only know machine instructions, so although different programming languages differ greatly
Large, then have to "translate" into machine instructions that the CPU can execute. And different programming languages,
Do the same job, write the amount of code, the gap is also very large.
For example, to accomplish the same task, the C language needs to write 1000 lines of code, and the Java language only needs to write 100 lines of code
Yes, and Python may only be 20 lines.
So Python is a fairly high level language.)
