Machine learning Python basics_opening
What is python?
Python is probably the most powerful language in the world.
Why learn python?
The author is learning Python to lay the foundation for learning artificial intelligence, so why Python? Because of the versatility of Python. There are more than 100,000 third-party Python libraries. These libraries make Python more familiar with specific tasks from traditional (such as web development, text processing) to the latest (such as AI and machine learning). The author majored in computer science at the university. I have studied Java, C, SpringMVC, etc. I have to say that Java is indeed a great ride. Many emerging languages such as Go and Python are more intelligent and convenient. They can be used as a glue language and can be used by cutting code fragments of other languages. For tasks completed in 100 lines of Java, C, and C++, Python may be only ten lines. Pai pat butt and leave.
The author's goal: artificial intelligence
Algorithms become more and more complex every day. The best example is Google's search algorithm. Uber is completely driven by algorithms. Although there are machine learning libraries in Java, you will find more about Python because the developer community is currently more inclined to use Python for machine learning. For now, machine learning is none other than Python, and the salary is quite impressive. As a new wave after Android, babies can’t miss it (it’s been hot in 2008). Now I’m looking for a job and look at Android interns. Terrible. The school still has to offer Android classes, and the baby feels distressed, so he can only find another lesson by himself.

The author will record every learning experience and history here. I hope you will give more support, encouragement and guidance. I also hope that students who come here with the same purpose as me can make progress with me.
