Python: Creates a dictionary with the same keys as the given dictionary and values generated by running the given function for each value

Python dictionary: Exercise-74 with Solution

Write a Python program to create a dictionary with the same keys as the given dictionary and values generated by running the given function for each value.

Sample Solution:

Python Code:

def test(obj, fn):
  return dict((k, fn(v)) for k, v in obj.items())
 
users = {
  'Theodore': { 'user': 'Theodore', 'age': 45 },
  'Roxanne': { 'user': 'Roxanne', 'age': 15 },
  'Mathew': { 'user': 'Mathew', 'age': 21 },
}
print("\nOriginal dictionary elements:")
print(users)
print("\nDictionary with the same keys:")
print(test(users, lambda u : u['age']))

Sample Output:

Original dictionary elements:
{'Theodore': {'user': 'Theodore', 'age': 45}, 'Roxanne': {'user': 'Roxanne', 'age': 15}, 'Mathew': {'user': 'Mathew', 'age': 21}}

Dictionary with the same keys:
{'Theodore': 45, 'Roxanne': 15, 'Mathew': 21}
