Python List: Exercise - 258 with Solution

Write a Python program to create a given flat list of all the keys in a flat dictionary.

  • Use dict.keys() to return the keys in the given dictionary.
  • Return a list() of the previous result.

Sample Solution:

Python Code:

def keys_only(students):
  return list(students.keys()) 
students = {
  'Laura': 10,
  'Spencer': 11,
  'Bridget': 9,
  'Howard ': 10,
}
print("Original directory elements:")
print(students)
print("\nFlat list of all the keys of the said dictionary:")
print(keys_only(students))

Sample Output:

Original directory elements:
{'Laura': 10, 'Spencer': 11, 'Bridget': 9, 'Howard ': 10}

Flat list of all the keys of the said dictionary:
['Laura', 'Spencer', 'Bridget', 'Howard ']
