Set exercises

gistfile1.txt

In your classroom, you have ten students that are born in a variety of months.                         

(1) Use sets or frozensets to tell if anyone was born in the summer.    

(2) Use sets or frozensets to tell who was born when the school year is not in session.   


The summer months are June, July, and August.

The ten students and their birthdays are:

Allen    January
Peggy    February
James    March
Alfred   April
Cain     February
Fitz     July
Janet    July
Ryan     June
Bryan    April
Filippe  October


The data will come to you as a nested list (also known as a list of lists or a multidimensional list).
for instance, here's the first three students:

```
[
  ["Allen", "January"],
  ["Peggy", "February"],
  ["James", "March"]
]
```
