Dec 1, 2024 · In this article, we will explore various methods to find second largest number in a list. The simplest way to find is by using a loop. Use a loop (for loop) to iterate over the list and keep two variables max1 and max2 to keep track of largest and second largest number of list.

Nov 25, 2019 · # Return the second highest value (ignoring ties) for a list of numbers. def runner_up(number_list): max1 = max(number_list) return max([i for i in number_list if i != max1]) Usage

Learn how to find the second largest number in a list using Python with this step-by-step guide and example code.

Mar 11, 2024 · This elegant one-liner uses Python’s built-in max() function with a filter to directly find the second largest number. It’s sleek and readable but not the most efficient due to double traversal over the list. Here’s an example: numbers = [7, 5, 6, 3, 8, 9] second_largest = max(filter(lambda x: x != max(numbers), numbers)) print(second ...

To find the second largest number, we simply accessed the element at the second-to-last index of the sorted list, sorted_list[-2]. This approach guarantees that the second largest number will be correctly identified regardless of the initial order of the list elements.

Jul 1, 2021 · Approach to find second largest number in a list. For executing this program in Python, there are multiple approaches we can follow: By sorting the list and printing the second maximum element. By removing the maximum number and then using max() function to get the second-largest number. By using the Brute-force approach.

Apr 19, 2025 · Write a Python program to find the second largest number in a list. Example - 1 : Example - 2 : Example - 3 : Example - 4 : Sample Solution: dup_items = set() .

We have created a function second_largest_num () and passed the list to it and it will return the second largest number from that list. We can also use Python sorted () function to find the second largest number from a list.

To find the second largest element in a list in Python, we can use sorting, the set() function, or simple iteration techniques. The most efficient method is to traverse the list while keeping track of the largest and second largest elements.

Mar 3, 2025 · For example, if the list is [4, 1, 7, 3, 9], the largest is 9, the smallest is 1, the second largest is 7 and the second smallest is 3. Let's explore different ways to solve this problem efficiently in Python.
