Question

Python 3

Define a function below, get_subset, which takes two arguments: a dictionary of strings (keys) to integers (values) and a list of strings. All of the strings in the list are keys to the dictionary. Complete the function such that it returns the subset of the dictionary defined by the keys in the list of strings. For example, with the dictionary ("puffin": 5, "corgi": 2, "three": 3) and the list ("three", "corgi"), your function should return {"corgi": 2, "three" : 3). Since dictionaries are unordered, you can add the keys to the new dictionary in any order.

Answer 1

def get_subset(a_dict, a_keys):
    result = {}
    for k in a_keys:
        if k in a_dict:
            result[k] = a_dict[k]
    return result


# Testing the function here. ignore/remove the code below if not required
print(get_subset({"puffin": 5, "corgi": 2, "three": 3}, ["three", "corgi"]))

{ 'three': 3, 'corgi': 2} Process finished with exit code 0
