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.

The function of the intermediary mode is to remove the coupling relationship between objects. After adding an intermediary object, all related objects communicate through the intermediary object instead of referencing each other. Therefore, when an object sends a change, only the intermediary object needs to be notified. Intermediaries loosely couple objects and can independently change their interaction.
