Consider the code in oops.py:

If you attempt to run this program using python, you will discover several

errors that prevent it from executing. There are $4$ distinct mistakes that need to

be corrected. Once the program has been completely debugged, it should look

like this in action:

~$/$ $ python oops.py

How many students are enrolled? $152$

We need $10$ teaching assistants

Fix this program so that it will run without error.

Note: we are trying to calculate one TF for every $15$ students, rounding

down.
