Python: Find the dimension of a given matrix

Python List: Exercise - 193 with Solution

Write a Python program to find the dimension of a given matrix.

Sample Solution:

Python Code:

def matrix_dimensions(test_list):
    row = len(test_list)
    column = len(test_list[0])
    return row,column

lst = [[1,2],[2,4]]
print("\nOriginal list:")
print(lst)
print("Dimension of the said matrix:")
print(matrix_dimensions(lst))
lst = [[0,1,2],[2,4,5]]
print("\nOriginal list:")
print(lst)
print("Dimension of the said matrix:")
print(matrix_dimensions(lst))
lst = [[0,1,2],[2,4,5],[2,3,4]]
print("\nOriginal list:")
print(lst)
print("Dimension of the said matrix:")
print(matrix_dimensions(lst)) 

Sample Output:

Original list:
[[1, 2], [2, 4]]
Dimension of the said matrix:
(2, 2)

Original list:
[[0, 1, 2], [2, 4, 5]]
Dimension of the said matrix:
(2, 3)

Original list:
[[0, 1, 2], [2, 4, 5], [2, 3, 4]]
Dimension of the said matrix:
(3, 3)
