How to find the positions of the N biggest values of a list in python
I am trying to find the N biggest values from a list and then print out their positions in the list If I would only focus on the max value it would look like this fr 8 4 1 1 12 print fr index max fr 4 However my aim is to get an output like 4 0 1 if it were for n 3 The 0 here shows the position of the second biggest value
Python program to find second largest number in a list, Output 45 The time complexity of the code is O nlogn where n is the number of elements in the list This is because the numpy argsort function has a time complexity of O nlogn for sorting the input list and selecting the second largest element from the sorted list takes constant time

Step 1 Declare a function for finding the second largest number Step 2 Use sort method to sort the list Step 3 Return the second last element in the list after sorting using negative indexing Step 4 Declare a list and take input or initialise values Step 5 Call the function Step 6 Print the value returned by the function Python Program 1 Python program to find second largest number in a list. To find the index of max value in a list using for loop we will use the following procedure First we will initialize a variable max index to 0 assuming that the first element is the maximum element of the list The first list contains the names of the students in the class The second list contains their respective grades These lists are parallel arrays which means that both of the arrays are the same size and each value represents part of a record students contains names and grades contains the grades those students have earned
