Top Three Building Heights

Write a Python program to find the heights of the top three buildings in descending order from eight given buildings.

Input:
0 ≤ height of building (integer) ≤ 10,000

Visual Presentation:

Sample Solution:

Python Code:

# Print statement to prompt the user to input the heights of eight buildings
print("Input the heights of eight buildings:")

# List comprehension to take input for the heights of eight buildings
l = [int(input()) for i in range(8)]

# Print statement to display the heights of the top three buildings
print("Heights of the top three buildings:")

# Sorting the list of building heights in ascending order
l = sorted(l)

# Printing the top three building heights in descending order using slicing and the 'sep' parameter for newlines
print(*l[:4:-1], sep='\n')

Sample Output:

Input the heights of eight buildings:
 25
 35
 15
 16
 30
 45
 37
 39
Heights of the top three buildings:
45
39
37

Explanation:

Here is the breakdown of the above Python exercise:

• The program starts by printing a statement prompting the user to input the heights of eight buildings.
• It uses list comprehension to create a list (l) containing the heights of eight buildings. The heights are converted to integers using int(input()).
• Another print statement is used to indicate that the program will display the heights of the top three buildings.
• The list of building heights (l) is sorted in ascending order.
• The heights of the top three buildings are printed in descending order using slicing (l[:4:-1]). The sep='\n' parameter ensures that each height is printed on a new line.
