Python Sort Returns None
“Sort Matrix by None frequency” refers to arranging a matrix in a specific order based on the frequency of occurrences of the “None” element within its elements.Sorting a matrix by None frequency involves arranging the elements of a matrix based on how often the value “None” appears within it. The goal is to organize the matrix in a way that highlights the distribution or prevalence of the “None” element, providing insights into the structure of the data.
Python – Sort Matrix by None frequency
In the world of Python programming, many developers aim to make matrix operations efficient and elegant in their code. A fascinating challenge that comes up is sorting a matrix based on how often the mysterious “None” element appears, adding an interesting twist to data manipulation in Python.
Given a Matrix, sort according to None elements frequency.
Example :
Input : test_list = [[None, None, 3, None], [12, 4, 5], [None, 3, 4]] Output : [[12, 4, 5], [None, 3, 4], [None, None, 3, None]] Explanation : 0, 1, 3 counts of None respectively.
