When it is required to sort matrix by row median, a method is defined that uses the ‘median’ method to determine the result.
Below is a demonstration of the same −
Example
from statistics import median
def median_row(row):
return median(row)
my_list = [[43, 14, 27], [13, 27, 24], [32, 56, 18], [34, 62, 55]]
print("The list is :")
print(my_list)
my_list.sort(key = median_row)
print("The result is :")
print(my_list)Output
The list is : [[43, 14, 27], [13, 27, 24], [32, 56, 18], [34, 62, 55]] The result is : [[13, 27, 24], [43, 14, 27], [32, 56, 18], [34, 62, 55]]
Explanation
The required packages are imported into the environment.
A method named ‘median_row’ is defined that takes row as a parameter, returns median of the row as output using ‘median’ method.
A list of list is defined and displayed on the console.
The list is sorted using ‘sort’ method and the key is specified as the previously defined method.
This is the output that is displayed on the console.
