Python - 按最大 ASCII 值对字符串进行排序

给定字符串列表，按字符串中的最大字符进行排序。

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. 

方法 #1：使用 sort() + max()

在这种情况下，使用sort()进行排序， max()用于从字符串中获取最大字符。

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))

输出：

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

方法 #2：使用 sorted() + lambda + max()

在这里，我们使用sorted()执行排序任务， lambda和max()用于输入获取最大字符的逻辑。

# 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))

输出：

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