Next, we will talk about the responsibility chain mode. There are multiple objects, each of which holds a reference to the next object, thus forming a chain on which requests are passed until an object decides to process the request. However, the sender does not know which object will process the request in the end, so the responsibility chain mode can be implemented to dynamically adjust the system without concealing the client. Let's look at the diagram first:
Differences between simple factories and factory methods: Simple factories and factory method patterns look very similar, especially specific factories in simple factories and factory methods. Simple factory, all things have been done in one place. However, the factory method creates a framework for subclasses to decide how to implement it. For example, in the factory method, the OrderPizza method creates a general framework to create pizza. The OrderPizza method relies on the factory method to create specific classes and make actual pizza. It is possible to decide what the actual products manufactured are by inheriting the factory. Simple factories do not have this flexibility.
The interface is more optimized and the operation is more convenient.

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.
