Use Python for data analysis: This book is a detailed version of Python's pandas package. Learn this to master some basic pandas commands. However, this is not the point, because pandas is too slow to produce a large amount of data and may collapse (I don't know if there is any improvement now-!) The point is, through studying this book, I feel a little about the data operation and am familiar with the basic data operation process. All the operations in this book can be replaced by native Python, and Pandas package is not needed. Finding feelings is very important.

When she came to Qingdao, she had to mention Kang Yue, the pride of Qingdao women's lifting in recent years. She was not only the champion of the National Games and the national champion, but also the world champion in the World Championship. In her heyday, Kang Yue's result in the 75kg category was 30kg higher than that of the domestic runner-up, almost the king of 75kg. Speaking of the day when I first arrived at the sports school, Liu Eryong still remembers vividly, "I saw her for the first time when I was selecting materials. The little girl was dirty in this school uniform. Her family lived in a small temporary house built by the sea. Her parents made a living by fishing for sea vegetables and her family was very poor. However, she has a very good talent and worked very hard after choosing a sports school. She almost never missed classes or asked for leave. Sometimes when she was injured, she was not allowed to practice and let her rest. The child cried and begged us whether my arm was injured and I could practice my legs and waist. Don't let me rest. With talent and hard work, Kang Yue was chosen by the province after less than two years of practice in our country. In the third year, she won the championship of the City Games and began to rule the women's 69 and 75 kg categories. She ruled for 10 years. The result of Shenyang National Games was 30 kg higher than that of the second place and 50 kg higher than that of the 2012 Olympic champion. This gap is amazing! "

Collision detection is automatically completed by BIM system, and detection reports are listed in real time to avoid manual inspection omission. Compared with traditional CAD methods, collision detection has higher efficiency and accuracy.

The reusability of the algorithm is poor. If there are similar algorithms in other places, but the rules are different, our codes cannot be used universally.

Liskov Substitution Principle, LSP (Richter Substitution Principle) means that subclasses must replace their parent types. In other words, in the process of software development, after the subclass replaces the parent class, the behavior of the program is the same. Only when the subclass replaces the parent class and the function of the software is not affected can the parent class be truly reused, and the subclass can also add new behaviors to the parent class. In order to look at an example of violation of LSP principles, the specific code is as follows:
However, it should be noted that if your Batman is not strong enough or there are too many casualties, the effect of such skills will be greatly reduced.
