Counting the word frequency in a list element in Python is a relatively common task - especially when creating distribution data forhistograms. Say we have a list['b', 'b', 'a']- we have two occurrences of "b" and one of "a". This guide will show you three different ways to coun...

Great job on implementing thecount_occurrencesfunction! 🎉 Your solution meets the task requirements and correctly counts the occurrences of a letter in a phrase, regardless of case. While your use of a loop is perfectly valid, consider exploring Python's built-in string methods likestr.count(...
