 ## Select and activate an environment
 
 By default, the Python extension looks for and uses the first Python interpreter it finds in the system path. If it doesn't find an interpreter, it issues a warning. On macOS, the extension also issues a warning if you're using the OS-installed Python interpreter, because you typically want to use an interpreter you install directly. In either case, you can disable these warnings by setting `python.disableInstallationCheck` to `true` in your user [settings](/docs/getstarted/settings.md).

-A conda environment is a Python environment that's managed using the `conda` package manager (see [Getting started with conda](https://conda.io/docs/user-guide/getting-started.html) (conda.io)).

Unlike virtual environments, which are scoped to a project, conda environments are available globally on any given computer. This availability makes it easy to configure several distinct conda environments and then choose the appropriate one for any given project.
