Arrays In Numpy

In this article, we will discuss arrays in NumPy.

Arrays

NumPy supports 2 types of arrays: -

Vectors are one-dimensional arrays. Here is an example

import numpy as np

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

Matrices are arrays of arrays. Here is an example

import numpy as np

my_matrix = [[1,2,3],[4,5,6],[7,8,9]]
print(np.array(my_matrix))

There are 2 ways of accessing an element: -

import numpy as np

my_matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])

# double bracket approach
print(my_matrix[0][1])

import numpy as np

my_matrix = np.array([[1,2,3],[4,5,6],[7,8,9]])

# single bracket approach
print(my_matrix[0, 1])
