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.
# Python program to find largest# number in a list # list of numberslist1 = [10, 20, 4, 45, 99] # sorting the listlist1.sort() # printing the last elementprint("Largest element is:", list1[-1]) |
Output:
Largest element is: 99
Method 2 : Using max() method
# Python program to find largest# number in a list # list of numberslist1 = [10, 20, 4, 45, 99] # printing the maximum elementprint("Largest element is:", max(list1)) |
Output:
Largest element is: 99
Method 3 : Find max list element on inputs provided by user
# Python program to find largest# number in a list # creating empty listlist1 = [] # asking number of elements to put in listnum = int(input("Enter number of elements in list: ")) # iterating till num to append elements in listfor i in range(1, num + 1): ele = int(input("Enter elements: ")) list1.append(ele) # print maximum elementprint("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:
# 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 codelist1 = [10, 20, 4, 45, 99]print("Largest element is:", myMax(list1)) |
Output:
Largest element is: 99
