In data processing, it is very common to perform overall operations on certain columns. pandas provides lots of methods for us to do this. The following are some methods we could choose. However, the performance of different methods varies greatly. When we have large amounts of data, the gap becomes more pronounced and has a greater impact on our productivity. In this lesson, we want to compare the ...
