- Python3.7 or higher
- Virtualenv
$ python --version
Python 3.7.1Note: You may need to explicitly install virtualenv, it depends on how you installed python.
Lets inspect our python/pip binaries:
$ which python3.7
/usr/local/bin/python3.7
$ which pip3.7
/usr/local/bin/pip3.7Notice that this is the system python/pip...
Now, let's create and activate virtualenv.
$ python3.7 -m venv venv
$ source venv/bin/activate
$ which python3.7
./venv/bin/python3.7
$ which pip3.7After activating the virtualenv python/pip are project specific!
Now lets install our project dependencies.
Since we have listed all of then in our
requirements.txt this is an easy task.
$ pip install -r requirements.txt

]This is very important, even if you don't believe it. To run the tests we use the following command:
$ pytest -v

==== x passed in 0.05 seconds ====$ mypy .$ flake8
Import sorting:
$ isort -rc persons test_persons flask_app.py connexion_app.pyCode formating:
$ black persons test_persons flask_app.py connexion_app.py
All done! ✨ 🍰 ✨
