Python Program to find out Largest among three numbers

The largest number among three numbers using four methods. In this article, we will learn how to find out the largest number among the three given numbers. These methods are totally different from each other but as a computer science student, you must have the idea.

largest number among three numbers

Frequency of Word in a python List

The largest number using if-else [ multiple checking ]

a = int(input('Enter first number :'))
b = int(input('Enter second number :'))
c = int(input('Enter third number :'))
if(a>b):
    if(a>c):
       print(a,' is the largest number')
    else:
       print(c,' is the largest number')
else:
   if(b>c):
       print(b,'is the largest number')
   else:
      print(c,' is the largest number')

The largest number – Second method

a = int(input('Enter first number :'))
b = int(input('Enter second number :'))
c = int(input('Enter third number :'))
lar = a
if(lar<b):
   lar = b
if(lar<c):
   lar = c
print(lar,' is the largest number')

The output of the above programs are as follows

Enter first number :4
Enter second number :56
Enter third number :3
56  is the largest number

Enter first number :45
Enter second number :3
Enter third number :56
56  is the largest number

The largest number – third method

a = int(input('Enter first number :'))
b = int(input('Enter second number :'))
c = int(input('Enter third number :'))
if(a > b and a > c):
    print(a, ' is the largest number')

if(b > a and b > c):
    print(b, ' is the largest number')

if(c > b and c > a):
    print(c, ' is the largest number')

The above largest number program uses logical operators to combine two python expressions using and operator.
The output is as follow

Enter first number :2
Enter second number :45
Enter third number :6
45  is the largest number

These are typical solution that you may have seen in different websites but I the last one is specific to Python that you can not implement in other programming languages.

The Largest number among three numbers

l1 = [10, 23, 45]
l1.sort()
print(l1[-1])

Now, I think you have the idea that for any problem we have multiple solutions. I hope you like these simple solutions to find out largest number among the three numbers.
