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:
Input : list1 = [10, 20, 4] Output : 20 Input : list2 = [20, 10, 20, 4, 100] Output : 100
Method 1 : Sort the list in ascending order and print the last element in the list.
Python3
# 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: 99
Method 2 : Using max() method
Python3
# 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
Method 3 : Find max list element on inputs provided by user
Python3
# 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: 99
Method 4 : Without using built in functions in python:
Python3
# 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: 99
Method: Use the max() and def functions to find the largest element in a given list. The max() function prints the largest element in the list.
Python3
# Python code # To find the largest number in a list def maxelement(lst): # displaying largest element # one line solution print ( max (lst)) # driver code # input list lst = [ 20 , 10 , 20 , 4 , 100 ] # the above input can also be given as # lst = list(map(int, input().split())) # -> taking input from the user maxelement(lst) # this code is contributed by gangarajula laxmi |
Output
100
