# Python – Sort Matrix by Maximum String Length

When it is required to sort matrix by maximum string length, a method is defined that takes a list as parameter and uses list comprehension and the ‘max’ and ‘len’ methods to determine the result.

Below is a demonstration of the same −

## Example

def max_length(row): return max([len(element) for element in row]) my_matrix = [['pyt', 'fun'], ['python'], ['py', 'cool'], ['py', 'ea']] print("The matrix is :") print(my_matrix ) my_matrix .sort(key=max_length) print("The result is :") print(my_matrix )

## Output

The matrix is : [['pyt', 'fun'], ['python'], ['py', 'cool'], ['py', 'ea']] The result is : [['py', 'ea'], ['pyt', 'fun'], ['py', 'cool'], ['python']]

## Explanation

A method named ‘max_length’ is defined that takes a list as a parameter, and gets the length of every element and uses ‘max’ to get the length of longest element.

Outside the method, a list of list is defined and is displayed on the console.

The list is sorted by specifying the method which was previously defined.

This is the output that is displayed on the console.
