Count occurrences of each word in a string
When solving this exercise, make sure to hold off on searching directly for the answer on Google/StackOverflow. 🚫🔍
This is a fairly general exercise and there are a number of answers to it. I'd like you to struggle to come to an answer or two (or five?) on your own.
I want you to write a function that accepts a string and returns a mapping (a dictionary or dictionary-like structure) that has words as the keys and the number of times each word was seen as the values.
Your function should work like this:
>>> count_words("oh what a day what a lovely day")
{'oh': 1, 'what': 2, 'a': 2, 'day': 2, 'lovely': 1}
>>> count_words("don't stop believing")
{"don't": 1, 'stop': 1, 'believing': 1}
