Using Counter on lists

Counter is a powerful tool for counting, validating, and learning more about the elements within a dataset that is found in the collections module. You pass an iterable (list, set, tuple) or a dictionary to the Counter. You can also use the Counter object similarly to a dictionary with key/value assignment, for example counter[key] = value.

A common usage for Counter is checking data for consistency prior to using it, so let's do just that.
