# Program to find the nth largest numbers in the list using Python

## Introduction

In this section of python programming, we will find the n largest numbers in the given list.

## Program

```list = [10, 15, 20, 70]

list1 = [1, 5, 7, 10]

n = int(input("Enter the nth number to find n largest number: "))

# Using sort()

list_copy = list

list.sort()

print("The {0} largest numbers in the given list {1} is {2}".format(n, list_copy, list[-n:]))

# Uisng traversal

list1_copy = set(list1)

def n_largest(list1, n):

output_list = []

for i in range(0, n):

max_ele = 0

for j in range(len(list1)):

if list1[j] > max_ele:

max_ele = list1[j];

list1.remove(max_ele);

output_list.append(max_ele)

output_list.sort()

return output_list

print("The {0} largest numbers in the given list {1} is {2}".format(n, list1_copy, n_largest(list1, n)))```

## Explanation

In the above python program, we have used simple traversal method and sort() function to find the nth largest elements in the given list. Using sort(), all the elements in the list are sorted in ascending order and after that we printed all the n elements from right that is required using slicing property of list.

In traversal method, we have found the max element, stored in the variable output_list and then removed from the list. The traversal process continues until we have found all the n elements required by the user.
