Find the number of rows and columns of a given matrix using NumPy

In the NumPy with the help of shape() function, we can find the number of rows and columns. In this function, we pass a matrix and it will return row and column number of the matrix.

Syntax:

shape()

Return: The number of rows and columns.

Example:

Python

import numpy as np


matrix= np.arange(1,9).reshape((3, 3))

# Original matrix
print(matrix)

# Number of rows and columns of the said matrix
print(matrix.shape)

Output:

[[1 2 3]
[4 5 6]
[7 8 9]]
(3,3)

Example :

Python

import numpy as np


matrix= np.arange(10,15).reshape((3, 2))

# Original matrix:
print(matrix)

# Number of rows and columns of the said matrix
print(matrix.shape)

Output

[[10 11]
[12 13]
[14 15]]
(3,2)
