Dictionaries are great because they allow us to reference items with non-numeric keys. However, that causes a problem because we cannot use our simple version of a for loop to iterate over what is stored in the dictionary. However, we have methods that give us particular elements from the dictionary as lists. Demonstrate your knowledge of dictionary methods by writing a function that counts the values in a dictionary.
Details
Write a function called count_values(a_dictionary,
a_value). It takes a dictionary and some arbitrary data type
that may or may not be in the dictionary. It should return an
integer, the number of times the specified value occurs in the
dictionary. count method.
Make sure your program handles all necessary cases gracefully. What additional test cases should you check?
Sample Test Cases
| Function Parameters | Sample Output |
|---|---|
| {"a": 1, "b": 2, "c": 2}, 2 | 2 |
| {"a": 1, "b": 2}, 2 | 1 |
