Python Programming Puzzles: Exercise-62 with Solution

Write a Python program to find the dictionary key whose case is different than all other keys.

Input:
{'red': '', 'GREEN': '', 'blue': 'orange'}
Output:
GREEN

Input:
{'RED': '', 'GREEN': '', 'orange': '#125GD'}
Output:
orange

Pictorial Presentation:

Python: Find the dictionary key whose case is different than all other keys.

Sample Solution:

Python Code:

def test(dict_data):
    for different in dict_data:
        if all(k.islower() != different.islower() for k in dict_data if k != different):
            return different
 
dict_data = {"red": "", "GREEN": "", "blue": "orange"}
print("Original dictionary key-values:")
print(dict_data)
print("Find the dictionary key whose case is different than all other keys:")
print(test(dict_data)) 
dict_data = {"RED": "", "GREEN": "", "orange": "#125GD"}
print("\nOriginal dictionary key-values:")
print(dict_data)
print("Find the dictionary key whose case is different than all other keys:")
print(test(dict_data))

Sample Output:

Original dictionary key-values:
{'red': '', 'GREEN': '', 'blue': 'orange'}
Find the dictionary key whose case is different than all other keys:
GREEN

Original dictionary key-values:
{'RED': '', 'GREEN': '', 'orange': '#125GD'}
Find the dictionary key whose case is different than all other keys:
orange

Python: Tips of the Day

Clamps num within the inclusive range specified by the boundary values x and y:

Example:

def tips_clamp_num(num,x,y):
  return max(min(num, max(x, y)), min(x, y))
print(tips_clamp_num(2, 4, 6))
print(tips_clamp_num(1, -1, -6))

Output:

4
