What is venv
venv is Python’s default virtual environment tool.
Basic usage
Create environment
venv creates a virtual environment for the Python version used to invoke it.
# If you only need one environment for the project
python -m venv venv
# If you are going to need multiple environments
python -m venv venv/myenv # Creates a nested dir
python -m venv <name-of-env> creates a directory in cwd.
The <name-of-env> can be anything you like, but venv is used the most by convention.
Just like node_modules, because venv exists within the project root, it is almost always added to .gitignore.
Activate environment
Assuming cwd is project root where venv directory exists,
source venv/bin/activate
Once activated, which python will point to
/Path/To/Project/venv/bin/python
Deactivate environment
deactivate
