# Specifying a Python version
If there is a specific version of Python that you need and you don't want to worry about any potential breaking changes due to patch updates (going from `3.7.5` to `3.7.6` for example), you should specify the exact major, minor, and patch version (such as `3.7.5`)
- The only downside to this is that set up will take a little longer since the exact version will have to be downloaded if the exact version is not already installed on the runner due to more recent versions
- MSI installers are used on Windows for this, so runs will take a little longer to set up vs Mac and Linux

You should specify only a major and minor version if you are okay with the most recent patch version being used
- For example, if you just want a `3.8` version of Python, and it doesn't matter if `3.8.1` is used or the more recent `3.8.2`,
- There will be a single patch version already installed on each runner for every minor version of Python that is supported
- The patch version that will be preinstalled, will generally be the latest and every time there is a new patch released, the older version that is preinstalled will be replaced
- Using the most recent patch version will result in a very quick setup since no downloads will be required since a locally installed version Python on the runner will be used
