The 1st day of learning Python

This is the first day of studying Python. From 3PM to now, It has taken me nearly 5 hours to 初步了解 python.

The first part is to 激活 路飞学城 python lessons. At the beginning, I thought it was not difficult to learn this machine language. However, I found myself totally wrong, this is because I have spent almost 3 hours to build 搭建学习环境, such as to download PYCHARM, which is an application to 编译代码.

After 安装并配置好 Pycharm APP, I started to learn python 1st and 2nd lessons. In these lessons, I have know about these parts of PYTHON.

The first one is about the history of python, when python is created, the recent rank of PYTHON in machine languages and its long term rank in machine languages. From the information given by Alex, I realize that python is a young machine language and nowadays it has become more and more popular and used in different parts. As for myself, the part I am most interested in is Artificial Intelligence and I know that if I want to work in AI 领域, I have to master in mathematics and be professional in Python. In order to reach my goal, I have to work hard and follow my teachers' advice.

The following part I know from this lesson is about 爬虫. Before this lesson, I have no knowledge about this thing. And I am very glad to know it through this class. 爬虫 means machines 模仿 people's way to copy codes from other 论坛/websites. This is because from this way, these 论坛/websites will not find these copyers are machines.

The thirs part is about which companies are using python now. Many international companies are using Python, such as UBER, YELP, GOOGLE, etc. Thus, you can know that python is so popular that more and more people and coraptions will use it. So I think my decision is right to learn this machine language and I 坚信 I can find a good job even start my own company with my professional python skill.

Last but not least, when I learn python, not only I am supposed to strenthen my professional skills but also to be keen on its future development. Only after putting eyes on the future, can we win the future!
