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)

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
