# Lab 8: Inverting a dictionary

## Building a reverse dictionary
Remember the <strong>cs111dict</strong> dictionary we built at the start of lab today?
 Wouldn't it be cool to be able to create a reverse
   dictionary where we use the values as the keys? We will return a
   dictionary where the keys are what used to be the values, and each
   key has a list of associated values (original keys).  For example,
our <strong>cs111dict</strong> has student names as keys and graduation
years as values.  The reverse dictionary of <strong>cs111dict</strong>
will have the graduation years as keys and the students' names
associated with those graduation years as values.  

For example,

{{-- update this example with current students and years --}}


```py
reverseCS111Dict = invert_dict(cs111dict) #reverse the cs111dict
reverseCS111Dict.keys() ==>
['2017', '2016', '2019', '2018']

reverseCS111Dict['2017'] ==>
 ['Lia', 'Hikari', 'Minjia', 'Kyra', 'Crystal', 'Sophie','Clarissa']
reverseCS111Dict['2018'] ==>
['Marissa', 'Alexandra', 'Caroline', 'Maya', 'Jessica', 'Andrea', 'Emma','Yasmin', 'Tanya', 'Heankel', 'Kaylie', 'Mojia', 'Madison', 'Mina', 'Rachel', 'Lauren', 'Maria-Alejandra', 'Shaina']
```
Write your <code>invertDictionary(dict)</code> function so that it takes a dictionary as a parameter and returns a new inverted dictionary. Note that the example above shows reversing the <strong>cs111dict</strong>, but your function should work for <i>any</i> dictionary.
