# Python Program to Find the Largest Among Three Numbers

To understand this example, you should have the knowledge of the following Python programming topics:

In the program below, the three numbers are stored in `num1`, `num2` and `num3` respectively. We've used the `if...elif...else` ladder to find the largest among the three and display it.

## Source Code

``````# Python program to find the largest number among the three input numbers

# change the values of num1, num2 and num3
# for a different result
num1 = 10
num2 = 14
num3 = 12

# uncomment following lines to take three numbers from user
#num1 = float(input("Enter first number: "))
#num2 = float(input("Enter second number: "))
#num3 = float(input("Enter third number: "))

if (num1 >= num2) and (num1 >= num3):
largest = num1
elif (num2 >= num1) and (num2 >= num3):
largest = num2
else:
largest = num3

print("The largest number is", largest)
``````

Output

```The largest number is 14
```

Note: To test the program, change the values of `num1`, `num2` and `num3`.

Before we wrap up, let's put your understanding of this example to the test! Can you solve the following challenge?

Challenge:

Write a function to find the smallest among three numbers.

• For example, for inputs 3, 1, and 2, the output should be 1.
