Python Program to Find Largest/Maximum of n Numbers

The objective of this Python post, you will see various Python programs that cover the following:

  • Python program to find largest of n numbers using max
  • Python program to find largest of n numbers without using built-in function

Python program to find largest of n numbers using max

  • Take input number for the length of the list using python input() function.
  • Initialize an empty list lst = [].
  • Read each number in your python program using a for loop.
  • In the for loop append each number to the list.
  • Use built-in python function max() to find the largest element in a list.
  • End of the program print the largest number from list.
lst = []

num = int(input('How many numbers: '))

for n in range(num):
    numbers = int(input('Enter number '))
    lst.append(numbers)
    
print("Maximum element in the list is :", max(lst))

Output

How many numbers:  5
Enter number  4
Enter number  6
Enter number  8
Enter number  9
Enter number  10
Maximum element in the list is : 10

Python program to find largest of n numbers without using built-in function

  • Take input number for the length of the list using python input() function.
  • Initialize an empty list lst = [].
  • Read each number in your python program using a for loop.
  • In the for loop append each number to the list.
  • Define a custom function, which is an accepted number list and used to find the largest number from list.
  • Call this custom function and store the function result.
  • End of the program print the largest number from list.
def find_max( list ):
    max = list[ 0 ]
    for a in list:
        if a > max:
            max = a
    return max


num = int(input('How many numbers: '))

lst = []

for n in range(num):
    numbers = int(input('Enter number '))
    lst.append(numbers)
    
print("Maximum element in the list is :", find_max(lst))

Output

How many numbers:  3
Enter number  1
Enter number  5
Enter number  7
Maximum element in the list is : 7
