### Source Code:

# Python program to find the largest number among the three input numbers # 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 1:

Enter first number: 10 Enter second number: 12 Enter third number: 14 The largest number is 14.0

### Output 2:

Enter first number: -1 Enter second number: 0 Enter third number: -3 The largest number is 0.0

### Explanation

In this program, we ask the user to input three numbers. We use the if…elif…else ladder to find the largest among the three and display it.
