Python: Create a flat list of all the keys in a flat dictionary

Python dictionary: Exercise-78 with Solution

Write a Python program to create a 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 test(flat_dict):
  return list(flat_dict.keys())
students = {
  'Theodore': 19,
  'Roxanne': 20,
  'Mathew': 21,
  'Betty': 20
}

print("\nOriginal dictionary elements:")
print(students)
print("\nCreate a flat list of all the keys of the said flat dictionary:")
print(test(students))

Sample Output:

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

Create a flat list of all the keys of the said flat dictionary:
['Theodore', 'Roxanne', 'Mathew', 'Betty']
