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.

I nodded at this passage, Understand that what Zhang Xiaobo said is indeed reasonable, It is not a lie, Here I think it is necessary to give you one thing about popular science. So we have to say something digressive: The result of a real bullet hitting a petrol tank is not the same as that shown in most movies. One shot can explode the petrol tank, But this is not the case, Although a pure metal projectile will rub against the air at a speed of hundreds of meters per second to generate equivalent heat, And will produce sparks after hitting the metal oil drum, But none of this is enough to ignite petrol, Especially for gasoline with a large total amount, to ignite gasoline, please remember one thing-open flame must be used. In addition, gasoline is a flammable item, but it is not an explosive item in the true sense. Only after reaching a certain total amount can explosion be caused. If the total amount is insufficient, it can only cause combustion without explosion.
