Python: Find the key of the maximum, minimum value in a dictionary

Python dictionary: Exercise-80 with Solution

Write a Python program to find the key of the maximum value in a dictionary.

  • Use max() with the key parameter set to dict.get() to find and return the key of the maximum value in the given dictionary.
  • Use min() with the key parameter set to dict.get() to find and return the key of the minimum value in the given dictionary.

Sample Solution:

Python Code:

def test(d):
  return max(d, key = d.get), min(d, key = d.get)

students = {
  'Theodore': 19,
  'Roxanne': 22,
  'Mathew': 21,
  'Betty': 20
}
print("\nOriginal dictionary elements:")
print(students)
print("\nFinds the key of the maximum and minimum value of the said dictionary:")
print(test(students))

Sample Output: 

Original dictionary elements:
{'Theodore': 19, 'Roxanne': 22, 'Mathew': 21, 'Betty': 20}

Finds the key of the maximum and minimum value of the said dictionary:
('Roxanne', 'Theodore')
