Directory tree

This "Getting Started" tutorial is broken into independent steps, starting with the smallest possible "single file WSGI app" example. Each of these steps introduces a topic and a very small set of concepts via working code. The steps each correspond to a directory in our workspace, where each step's directory is a Python package.

As we develop our tutorial, our directory tree will resemble the structure below:

quick_tutorial
    │── env
    `── request_response
        `── tutorial
        │   │── __init__.py
        │   │── tests.py
        │   `── views.py
        │── development.ini
        `── setup.py

Each of the directories in our quick_tutorial workspace (e.g., request_response) is a Python project (except as noted for the hello_world step). The tutorial directory is a Python package.

For most steps you will copy the previous step's directory to a new directory, and change your working directory to the new directory, then install your project:

$ cd ..; cp -r package ini; cd ini
$ $VENV/bin/pip install -e .

For a few steps, you won't copy the previous step's directory, but you will still need to install your project with $VENV/bin/pip install -e ..
