Environment Isolation and Dependency Management

Information on development environment and dependency:

Environment Isolation:

• System installed python should never be used for development. Isolate your development.
• Any of the following can be used for python isolation:
  • pyenv. Recommended as this supports local python install and multiple python versions.
  • virtualenv. Third Party
  • venv. Inbuilt python -m venv
• Use pip for installing packages if not using poetry.

info

Docker based containerized python can be used as well. Official images here. It is better to use virtualenvs in docker as well rather than root based user.

Dependency Management:

• poetry is recommended as it handles dependency as well as build system.
• You can use setuptools and setup.py as well for requirements handling through requires. They must be used for install-able modules.
• requirements.txt style should be avoided although you may come across this style a lot.
