Python - Sort Strings by Maximum ASCII value

Python – Sort Strings by Maximum ASCII value

Last Updated : 11 Oct, 2020

Given strings list, perform sort by Maximum Character in String.

Input : test_list = [“geeksforgeeks”, “is”, “best”, “cs”]
Output : [“geeksforgeeks”, “is”, “cs”, “best”]
Explanation : s = s = s < t, sorted by maximum character.

Input : test_list = [“apple”, “is”, “fruit”]
Output : [“apple”, “is”, “fruit”]
Explanation : p < s < t, hence order retained after sorting by max. character.

Method #1 : Using sort() + max()

In this, sorting is performed using sort() and max() is used to get maximum character from Strings.

Python3

# Python3 code to demonstrate working of 
# Sort Strings by Maximum Character 
# Using sort() + max() 
  
# get maximum character fnc. 
def get_max(sub): 
  
    # returns maximum character 
    return ord(max(sub)) 
  
  
# initializing list 
test_list = ["geeksforgeeks", "is", "best", "for", "cs"] 
  
# printing original lists 
print("The original list is : " + str(test_list)) 
  
# performing sorting 
test_list.sort(key=get_max) 
  
# printing result 
print("Sorted List : " + str(test_list)) 

Output:

The original list is : [‘geeksforgeeks’, ‘is’, ‘best’, ‘for’, ‘cs’]
Sorted List : [‘for’, ‘geeksforgeeks’, ‘is’, ‘cs’, ‘best’]

Method #2 : Using sorted() + lambda + max()

In this, we perform task of sorting using sorted(), lambda and max() are used to input logic of getting maximum character.

Python3

# Python3 code to demonstrate working of 
# Sort Strings by Maximum Character 
# Using sorted() + lambda + max() 
  
# initializing list 
test_list = ["geeksforgeeks", "is", "best", "for", "cs"] 
  
# printing original lists 
print("The original list is : " + str(test_list)) 
  
# performing sorting using sorted() 
# lambda function provides logic 
res = sorted(test_list, key=lambda sub: ord(max(sub))) 
  
# printing result 
print("Sorted List : " + str(res))
