Question

Write a python program to enter three numbers and display the largest number.Use nested if statement.

Answer 1

# 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 between",num1,",",num2,"and",num3,"is",largest)

Answer 2

The easiest possible way to do this kind of a problem is to use the max() function in the list functions.

_______________________________________________________

Let's say we have an empty list and then we keep adding 3 inputs from the user to the list. I will use range() function to take inputs. It is much more stable.

_____________________________________________________

After taking the input, we will immediately add these numbers into a list called numbers and the call max(numbers) and we will be returned with the maximum number in the list.

CODE:

numbers = []

for i in range(3):

   num = float(input(f'Enter your number({i}):'))

   numbers.append(num)

print(f'The greatest number is {max(numbers)}')

INPUT:

1,2,4

OUTPUT:

4
