Accept three numbers from the user and display the second largest number.

Sure, here is a step-by-step guide on how to solve this problem in Python:

1. First, you need to get the three numbers from the user. You can use the input() function in Python to get user input. Remember that input() returns a string, so you need to convert the input to an integer using the int() function.

num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
num3 = int(input("Enter third number: "))

2. Next, you need to determine the second largest number. You can do this by using the sorted() function in Python, which sorts a list of numbers in ascending order.

numbers = [num1, num2, num3]
sorted_numbers = sorted(numbers)

3. The second largest number is now the second number in the sorted list. You can access it by using index 1 (since Python list indices start at 0).

second_largest = sorted_numbers[1]

4. Finally, you can print the second largest number using the print() function.

print("The second largest number is: ", second_largest)

So, the complete Python code would look like this:

num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
num3 = int(input("Enter third number: "))

numbers = [num1, num2, num3]
sorted_numbers = sorted(numbers)

second_largest = sorted_numbers[1]

print("The second largest number is: ", second_largest)
