Directions for Lab: quadratic.py

Follow the directions at PyCharm Debugging. We have provided starter code at quadratic.py; use this instead of the Solver class version on the PyCharm Debugging webpage. Read over the PyCharm Debugging webpage, and demonstrate that you can step through the code and view the d variable prior to the square root function call. Explain the solve() code to your duck, and determine what changes are required to fix the code. Modify code as needed, and submit the code to zyLab.

GIVEN CODE FOR quadratic.py :
