Choosing the correct version of Python

lsp-pyright will try its best to select the correct version of the python executable to use. It will do so by iteratively executing different search functions, going from most precise to most general.

The list and order of the list can be modified by customizing lsp-pyright-python-search-functions. By default the order is:

• Look for a parent directory with a virtual-environment named .venv or venv via lsp-pyright--locate-python-venv.
• Look for a python executable on your PATH via lsp-pyright--locate-python-python.
