原文:https://www . geeksforgeeks . org/python-find-the-sublist-with-value-in-给定嵌套列表/
给定一个列表列表，任务是在第二列中找到具有最大值的子列表。
示例:
Input : [['Paras', 90], ['Jain', 32], ['Geeks', 120],
['for', 338], ['Labs', 532]]
Output :['Labs', 532]
Input: [['Geek', 90], ['For', 32], ['Geeks', 120]]
Output: ['Geeks', 120]
下面是一些完成上述任务的任务。
方法#1:使用λ
# 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)
Output:
输入列表为:[['Paras '，90]，['Jain '，32]，['Geeks '，120]，['for '，338]，['Labs '，532]] 输出列表为:['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)
Output:
输入列表为:[['Paras '，90]，['Jain '，32]，['Geeks '，120]，['for '，338]，['Labs '，532]] 输出列表为:['Labs '，532]
