Associate a version of Python with your project. When active, renv will
take care of capturing your Python dependencies when renv::snapshot() is called,
and installing your Python dependencies when renv::restore() is called.
use_python(python = NULL, type = "virtualenv", name = NULL, ...,
project = NULL)The path to a Python binary. This can be the path to a Python
binary on the system, or the path to a Python binary within an
already-existing Python environment. If NULL, the RETICULATE_PYTHON
environment variable is checked; if that is not set, then the default
version of Python on the PATH is used instead.
The type of Python environment to use. By default, a project-local
virtual environment will be created with the requested version of Python,
as supplied by python. Ignored if the requested version of python lives
within a pre-existing Python environment.
When type is "virtualenv" or "conda", this argument can be
used to supply the name or path that should be used for the associated
Python environment. Ignored if the requested version of python lives
within a pre-existing Python environment.
Optional arguments; currently unused.
The project directory. If NULL, then the active
project will be used. If no project has been specifically activated,
the current working directory is used.
