Python - 2-D Array
Two dimensional array is an array within an array. It is an array of arrays. In this type of array the position of an data element is referred by two indices instead of one. So it represents a table with rows an dcolumns of data.
In the below example of a two dimensional array, observer that each array element itself is also an array.

Consider the example of recording temperatures 4 times a day, every day. Some times the recording instrument may be faulty and we fail to record data. Such data for 4 days can be presented as a two dimensional array as below.

Accessing Values
The data elements in two dimesnional arrays can be accessed using two indices. One index referring to the main or parent array and another index referring to the position of the data element in the inner array.If we mention only one index then the entire inner array is printed for that index position.

Python | Using 2D arrays/lists the right way
Python provides many ways to create 2-dimensional lists/arrays. However one must know the differences between these ways because they can create complications in code that can be very difficult to trace out. Lets start by looking at common ways of creating 1d array of size N initialized with 0s.

Python 2D Arrays: Two-Dimensional List Examples
Array is a data structure used to store elements. An array can only store similar types of elements. A Two Dimensional is defined as an Array inside the Array. The index of the array starts with 0 and ends with a size of array minus 1. We can create ‘n’ number of arrays in an array.
In the above image, we can see that an index uniquely identifies each array element.
