Letter Count Histogram¶
The previous lab wrote a function to return a dictionary of letter counts. In an earlier chapter, we wrote a turtle program that could draw a histogram.
Combine these two ideas together to create a function that will take a string and create a histogram of the number of times each letter occurs. Make sure it is in alphabetical order from left to right.
- Count the number of times each letter occurs. Keep the count in a dictionary.
- Get the keys from the dictionary, convert them to a list, and sort them.
- Iterate through the keys, in alphabetical order, getting the associated value (count).
- Make a histogram bar for each.
