Python Basic - 1: Exercise-32 with Solution

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

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

Pictorial Presentation:

Python: Find heights of the top three building in descending order from eight given buildings

Sample Solution:

Python Code:

print("Input the heights of eight buildings:")
l = [int(input()) for i in range(8)]
print("Heights of the top three buildings:")
l = sorted(l)
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

Python: Tips of the Day

Merges two or more lists into a list of lists, combining elements from each of the input lists based on their positions

Example:

def tips_merge(*args, fill_value=None):
  max_length = max([len(lst) for lst in args])
  result = []
  for i in range(max_length):
    result.append([
      args[k][i] if i < len(args[k])
	  else fill_value for k in range(len(args))
    ])
  return result
print(tips_merge(['x', 'y'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False])) 
print(tips_merge(['x'], [1, 2], [True, False], fill_value = '_')) 

Output:

[['x', 1, True], ['y', 2, False]]
[['x', 1, True], [None, 2, False]]
[['x', 1, True], ['_', 2, False]]
