  • a suite of tests for your project

Requirements

• Passing unit tests
• No PEP8 or Pyflakes warnings or errors

Normal Mode

Create a simple web application that works as a calculator. The first page, which you get via a GET request, should have a form with two text boxes, a dropdown box for the operation (+, -, *, /) and a button to calculate.

The form uses POST to go to a second screen which shows the results of your calculation.

Hard Mode

In addition to the requirements from Normal Mode:

1. The form should also appear on the second page -- the calculation results page. The first operand should be filled in with the results of the previous calculation.

2. Add Foundation or Bootstrap to your application to make it look nicer.
