including things like web development, machine learning etc.
包括网络开发 机器学习等
Python is also designed to be human readable.
Python的设计很通俗易懂
So that way, if you’re not real in tune with a lot of different like C++ syntax
也就是说 如果你不太喜欢
and things like pointers and so forth,

some really good best practices

that you’ll want to use with any programming language
你可以将这些实践操作
that you might be programming with.
用于任何你可能使用的编程语言
But it’s also a great advanced programming language as well.

That again, Python is flexible.
再强调一遍 Python很灵活
So that Python can grow with you,

As you start digging deeper into say machine learning,
当你深入研究所谓的机器学习时
Python can come along with you for the ride.
Python可以一直伴你左右
You don’t necessarily need to go out and learn another language.
你不需要再去学习新的编程语言
Finally, Python has a fantastic community
最后 Python有一个很棒的社区
that if you’re thinking, “Hey, I want to do”,

Fill in the blank,
在社区里搜索一下
chances are somebody has been nice enough to creat a package

So the last question then is,
好了 最后一个问题就是
what can I build with Python?

The answer is pretty much anything.
答案是:任何你想要的
So you could do machine learning models,
