An active engineer explains how to handle 2D arrays in Python [for beginners]
I will explain how to handle 2D arrays in Python.
If you're not familiar with Python in the first place, read an article that explains what Python is and get a better understanding.
This article is based on the contents of the TechAcademy online boot camp Python course.
What is a two-dimensional array
A one-dimensional array is an array with one dimension, and multiple elements are arranged on a straight line.
(Example) [1,2,3,4,5,6]
A two-dimensional array is an array with two dimensions and is also called a matrix.
(Example) [[1,2,3], [4,5,6]]
The following is a visually easy-to-understand description.
[[1,2,3], [4,5,6]]
Similarly, you can define an array with 3 or 4 dimensions.
How to make a two-dimensional array
To create a 2D array in Python, write as follows.
xs = ...
