Python|在给定的嵌套列表中查找具有最大值的子列表

给定一个列表列表，任务是在第二列中找到最大值的子列表。

例子：

Input : [['Paras', 90], ['Jain', 32], ['Geeks', 120],
                        ['for', 338], ['Labs', 532]]
Output :['Labs', 532]

Input: [['Geek', 90], ['For', 32], ['Geeks', 120]]
Output: ['Geeks', 120]

以下是实现上述任务的一些任务。

方法 #1：使用 lambda

# Python code to find maximum value 
# in second column of list of list
  
# Input list initialization
Input = [['Paras', 90], ['Jain', 32], ['Geeks', 120],
                        ['for', 338], ['Labs', 532]]
# Using lambda 
Output = max(Input, key = lambda x: x[1])
  
# printing output
print("Input List is :", Input)
print("Output list is : ", Output)

输出：

Input List is : [[‘Paras’, 90], [‘Jain’, 32], [‘Geeks’, 120], [‘for’, 338], [‘Labs’, 532]]
Output list is : [‘Labs’, 532]

方法 #2：使用 itemgetter

# Python code to find maximum value 
# in second column of list of list
  
# Importing
import operator 
  
# Input list initialization
Input = [['Paras', 90], ['Jain', 32], ['Geeks', 120],
                        ['for', 338], ['Labs', 532]]
# Using itemgetter
Output = max(Input, key = operator.itemgetter(1))
  
# Printing output
print("Input List is :", Input)
print("Output list is : ", Output)

输出：

Input List is : [[‘Paras’, 90], [‘Jain’, 32], [‘Geeks’, 120], [‘for’, 338], [‘Labs’, 532]]
Output list is : [‘Labs’, 532]
