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.
