N Python Tutorial – Complete Guide

Welcome to an exciting journey into learning n python. If you’ve ever wondered how to expand your Python skills or make your code more efficient, you’re in the right place. We’re going to dive deep into Python’s capabilities, giving you practical examples and insights that will boost not only your understanding but your coding abilities.

What is n Python

Python is a highly sought-after language in the coding community, thanks to its simplicity and robustness. n python takes this a step further, focusing on the efficient handling of large data – both in terms of size and dimensionality.

n python is used to bring high-level, expressive and flexible coding to large datastreams. By offering a seamless interaction with huge datasets, it removes the common complexity barriers, letting you focus on the coding mechanics rather than data wrangling.

Why should I learn it?

The ability to handle big data efficiently and effectively is an invaluable skill in today’s data-centric world. Whether you’re keen on high-level analytics, machine learning, or game development, becoming proficient with n python will equip you with the tools to excel in your coding journey.

While this might feel daunting, don’t worry. You’re not in this alone. We’ll be guiding you through step by step, ensuring that you come out the other side with a solid understanding of n python and a whole new set of coding skills.

Getting Started with n Python

To begin with, let’s demonstrate how to install the n dimension array library, numpy. It’s a very straightforward process assuming you have already installed Python. Just type the following command into your terminal:

pip install numpy


Basic Array Creation

Python utilizes something known as a list which can be thought as the equivalent of arrays in other programming languages. With n python, or numpy, we can also create multi-dimensional arrays. Let’s explore some examples:

import numpy as np

one_dimen_array = np.array([1, 2, 3])

two_dimen_array = np.array([[1,2,3], [4,5,6]])


Array Attributes

Numpy arrays come with attributes that provide helpful information. We have attributes such as ndarray.ndim (number of dimensions), ndarray.shape (dimensions of array) and ndarray.size (number of elements in the array). Let’s create an array and find these attributes:

import numpy as np

two_dimen_array = np.array([[1,2,3], [4,5,6]])

print("Number of dimensions: ", two_dimen_array.ndim)
print("Shape: ", two_dimen_array.shape)
print("Size: ", two_dimen_array.size)


Array Initialization

Numpy also offers various ways to initialize arrays. We can create an empty array, array of ones, array of zeros, matrix with diagonal elements as ones and others as zeros(Identity matrix).

import numpy as np

empty_array = np.empty([3, 2])
print("Empty array:\n", empty_array)

ones_array = np.ones([3, 2])
print("\nArray of ones:\n", ones_array)

zeros_array = np.zeros([3, 2])
print("\nArray of zeros:\n", zeros_array)

identity_matrix = np.eye(3)
print("\nIdentity matrix:\n", identity_matrix)


Here, we have just touched on the basics of n dimensional arrays. We will expand more on operations, manipulation, and other functionalities in the next part of this tutorial. Stay tuned for that!

Array Operations

Arrays in numpy allow for efficient element-wise operations, like addition, subtraction, multiplication, etc. Let’s check a few of them:

import numpy as np

Arr1 = np.array([1, 2, 3])
Arr2 = np.array([4, 5, 6])

print("Addition: ", Arr1 + Arr2)
print("Subtraction: ", Arr1 - Arr2)
print("Multiplication: ", Arr1 * Arr2)
print("Division: ", Arr1 / Arr2)


Array Reshaping

Numpy also offers functionalities like reshaping an array.
Point to be noted here is that the reshaping of array should be compatible to the size of original array.

import numpy as np

one_dimen_array = np.array([1, 2, 3, 4, 5, 6])

two_dimen_array = one_dimen_array.reshape(2,3)
print("Two Dimensional Array: ")


Array Indexing and Slicing

Accessing and modifying elements in an array is an important aspect of data manipulation. Here’s how to access and alter elements:

import numpy as np

Arr = np.array([1, 21, 3, 7, 5, 4, 6, 22, 9])
print("Third element of array: ", Arr[2])

Arr[2] = 400
print("New array after modification: ", Arr)


Furthermore, we can also slice arrays to get a sub-array of given elements.

import numpy as np

Arr = np.array([1, 21, 3, 7, 5, 4, 6, 22, 9])
print("Elements from index 2 to 5: ", Arr[2:5])


Array Broadcasting

Broadcasting in numpy allows for arithmetic operations on arrays of different shapes. Here’s an example:

import numpy as np

Arr1 = np.ones([3, 3])
Arr2 = np.array([1, 2, 3])

print("Array after Broadcasting: ")
print(Arr1 + Arr2)


Learning n python is a practical tool for handling multi-dimensional array. Building simple conversations about it can make learning more exciting, inspiring and broad.
