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

Python List: Exercise - 258 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 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 ']

Python: Tips of the Day

Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:

Example:

def tips_check_prop(fn, prop):
  return lambda obj: fn(obj[prop])
check_age = tips_check_prop(lambda x: x >= 25, 'age')
user = {'name': 'Owen', 'age': 25}

print(check_age(user))

Output:

True
