Find Maximum Value in a List in Python
Created: November-16, 2020 | Updated: December-10, 2020
This tutorial will demonstrate how to find the maximum value in a list in Python.
A few scenarios and data types will be covered, from a simple integer list to a more complex structure such as an array within an array.
Python List max() Method
Find Maximum Value in List in Python
In this article, we will learn to find the maximum value in a list in Python. We will use some built-in functions, simple approaches, and some custom codes as well to understand the logic. Let's first have a quick look over what is a list in Python and how can we find the maximum value or largest number in a list.
Python max()
In this tutorial, we will learn about the Python max() function with the help of examples.
The max() function returns the largest item in an iterable. It can also be used to find the largest item between two or more parameters.
Example
numbers = [9, 34, 11, -4, 27]The max() function has two forms:
# to find the largest item in an iterable max(iterable, *iterables, key, default) # to find the largest item between two or more objects max(arg1, arg2, *args, key)Python program to find largest number in a list
Given a list of numbers, the task is to write a Python program to find the largest number in given list.
Examples:
Method 1 : Sort the list in ascending order and print the last element in the list.
|
# Python program to find largest
# number in a list
# list of numbers
list1 = [10, 20, 4, 45, 99]
# sorting the list
list1.sort()
# printing the last element
print("Largest element is:", list1[-1])
|
Output:
Largest element is: 99Method 2 : Using max() method
|
# Python program to find largest
# number in a list
# list of numbers
list1 = [10, 20, 4, 45, 99]
# printing the maximum element
print("Largest element is:", max(list1))
|
Output:
Largest element is: 99Method 3 : Find max list element on inputs provided by user
|
# Python program to find largest
# number in a list
# creating empty list
list1 = []
# asking number of elements to put in list
num = int(input("Enter number of elements in list: "))
# iterating till num to append elements in list
for i in range(1, num + 1):
ele = int(input("Enter elements: "))
list1.append(ele)
# print maximum element
print("Largest element is:", max(list1))
|
Output:
Enter number of elements in list: 4 Enter elements: 12 Enter elements: 19 Enter elements: 1 Enter elements: 99 Largest element is: 99Method 4 : Without using built in functions in python:
|
# Python program to find largest
# number in a list
def myMax(list1):
# Assume first number in list is largest
# initially and assign it to variable "max"
max = list1[0]
# Now traverse through the list and compare
# each number with "max" value. Whichever is
# largest assign that value to "max'.
for x in list1:
if x > max :
max = x
# after complete traversing the list
# return the "max" value
return max
# Driver code
list1 = [10, 20, 4, 45, 99]
print("Largest element is:", myMax(list1))
|
Output:
Largest element is: 99Attention geek! Strengthen your foundations with the Python Programming Foundation Course and learn the basics.
