Question 8 (STUCK)
'''
8. What are the top 3 shapes sighted, and how many sightings were there for each?
Note: Consider all sightings stored in "ufosightings".
- Create a new list "sightings_shapes" containing values from the "shape" column in ufosightings.
- Create a new dictionary "count" with values of that column as keys and the counts as values.
- Get a list of the dictionary keys and values using the items() method. This will return a list of key:value pairs.
Sort the list of key:value pairs in reverse order, from greatest (most sightings) to least.
Get the top 3 and store in "top3shapes". Print the result.
