Geometry Calculator Web

The is a simple Flask-based web application that uses a Geometry Calculator Tool created out of assignments from my Intro to Programming course. This project demonstrates simple implementations of the following methodologies:

• Unit testing
• Virtual environments for code deployment
• And a dynamic web application using Python Flask as the framework

App Prep & Run Steps

To use this code do the following:

1. Pick a location on disk and clone this code into a local repository:

   git clone https://github.com/foxster14/geometry_calculator_python_flask_web_app

   (Alternatively the new GitHub CLI could also be used)

   A new directory will be created: geometry_calculator_python_flask_web_app "cd" into it.

   cd ./geometry_calculator_python_flask_web_app

2. Create a Python Virtual Environment

   It is advisable to use a Python Virtual Environment to keep this app's dependencies separate from other Python dependencies on the target machine. To create a Virtual Environment do the following from within the geometry_calculator_web directory:

   Unix OS's:

   python3 -m venv venv

   Windows:

   python -m venv venv

3. Activate the Virtual Environment:

   Unix OS's:

   source venv/bin/activate

   Windows:

   venv\Scripts\activate.bat

4. Install App Dependencies Using the Python Package Tool:

   Rather than using pip to install the required packages, such as Flask, etc., all dependencies are in the requirements.txt file.

   In a virtual environment that was create using Python 3, on Unix OS's there no need to use pip3. You can, but pip also works in this instance.

   pip install -r requirements.txt

   Windows:

   pip install -r requirements.txt

5. Run the Application:

   python GeometryCalcWeb.py

   The App should now be running on port 5000. Access it via localhost:5000 --or-- 127.0.0.1:5000

Python Unit Testing

This repo also contains two sample Unit Tests. One for the cylinder.py module. One for the GeometryCalcWeb.py program.

You can run them by doing the following:

python cylinderTest.py

python GeometryCalcWeb.py
