I’ve been trying and failing to create a function that outputs the following from the following inputs:

Input:

print(len(word_counter(["Dog", "Cat", "Dog", "Mouse", "Cat"])))

Output:

3

Input:

result = word_counter(["Dog", "Cat", "Dog", "Mouse", "Cat"])

or

result = sorted(list(result))
print(result)

Output:

['Dog', 'Mouse', 'Cat']

Input:

print(word_counter(["Dog", "Cat", "Dog", "Mouse", "Cat"]).get("Dog"))

Output:

2

Any comments that could even remotely guide me in the right direction would be greatly appreciated. I know that I probably need to use a dictionary and include for- and if-statements somehow.
