Make the Project Installable

create setup.py file to describes your project and the files that belong to it.

Python needs another file named MANIFEST.in to tell what this other data is.

Use pip to install your project in the virtual environment.

pip install -e .

pip list

This tells pip to find setup.py in the current directory and install it in editable or development mode.

Testing

use pytest and coverage to test and measure your code.

pip install pytest coverage

pytest -v

coverage run -m pytest

coverage html

Build

pip install wheel
python setup.py bdist_wheel

You can find the file in dist/flaskr-1.0.0-py3-none-any.whl. The file name is the name of the project, the version, and some tags about the file can install.
