The scientific computing package in Python numpy is a great extension tool, numpy the most common is the operation of the array Ndarray, part of the operation and Python's built-in list (its stitching is append and extend) overlap, However, to be aware of the use of the way, in addition, for the Ndarray array splicing has its own way. Next, I'll introduce the four types of numpy arrays I know:

Method 1 is a more traditional use, in another pandas library for data operations, which corresponds to the concat, that is, the connection

Method 2 is another shortcut, where h should be horizontal meaning, V should be vertical

Method 3 can also be divided into two categories, where the first category is the second type of abbreviation, but also I prefer the use, because the easiest.

Method 4 is the same as the built-in list, use to pay attention to the setting of the Axis

The visual sense, but many know how to choose a number of ways to select their favorite one, see other operations also know its role, why not?
