Python project template

Objective

This repository intends to stand a reliable and consistent procedure for setting up a development environment for python projects.

Thus, the main dependencies for the project's structure organization are the following:

setup.sh: Sets up a proper and isolated python environment, designed for both development and production purposes;
pyproject.toml: Describes the project's build specification, according to its specification;
.editorconfig: Applies formatting to whole repository content for any compatible editors, as depicted in its site;
.gitignore: Usual ignoring file against a python project's build, caching files and its corresponding editors.

There are other files in repository but not essential for a project initialization. such this file, LICENSE, CI/CD configuration and any other ones.

The setup.sh file is going to run the following:

shellcheck's check in order to verify its own content's syntax;
For both:
- Downloads each aforementioned project management tools and installs as the way its corresponding procedure recommends;
- Initiates its corresponding program and exports them to PATH variable;
- Appends to ~/.bashrc the code snippet once in order to activate them automatically as a new shell is spawned.
For pyenv:
- Creates a virtualenv activation using the repository's recipient folder name and according to the PROJ_VER variable:
  - Skips this step if a environment had already been activated as described above;
  - The current activation will be cleaned up if does not correspond to the way this script sets it.
For pypoetry:
- Verifies for poetry updates;
- Instructs the program to not creating virtual environments for itself;
- If pyproject.toml is present:
  - Checks if this file is valid;
  - Updates the activated virtualenv's dependencies.
    - (Creates a new one with its default setting if the file absent).
- Adds some useful development dependencies to the activated virtualenv if absent.
  - (If a poetry.lock file does not exist in the repository and a one is generated during the execution, it is going to be removed afterwards).

In addition to that, it does:

Install other complementary development tools such as docker, terraform and AWS client;
Create .gitignore and .editorconfig files as previously described if the corresponding one is absent.
