How to Implement Python 2D Array with Example

To implement a 2D array in Python, use these two ways. Use list object as a 2D array.Use the numpy library to create a two-dimensional array.

In every programming language, an array is represented as an array[index]. The index is the number that states the location number of a particular item in the memory location.

Since array uses sequential memory, therefore the index numbers are also continuous. It is quite obvious to note that the array indexing starts at 0 and ends at n-1, where n is the size of an array.

Python array

An array in Python is a linear data structure that contains an ordered collection of items of the same data type in the sequential memory location. There is no specific array object in Python because you can perform all the operations of an array using a  Python list.

We can define the list as a single-dimensional array using the following syntax.

array_name = [ ]

You can initialize the Python array using the following code.

## app.py

data = [11, 21, 19, 18, 46]
print(data)

Python Programming: A Beginner’s Guide

Python is an interpreted, high-level, powerful general-purpose programming language. You may ask, Python’s a snake right? and Why is this programming language named after it?

Python Lists I and How do we create an empty list in Python?

One of the standout features of Python is its powerful collection of built-in data structures, which can be classified as either mutable or immutable. Lists, Sets and Dictionaries are mutable, meaning their contents can be altered after creation. Tuples and Strings are immutable, i.e., initial values…

Python Lists II and Can we append to lists?

In the previous post, we had gone through list creation, indexing and slicing. Let us explore the power of lists further. Can we append to lists? The operation of adding elements at the end of a mutable sequence is known as append. Since lists can be modified (aka mutable), it is perfectly legal to apply this operation on objects of type list.
