## What changes were proposed in this pull request? I would like to change ```bash if hash python2.7 2>/dev/null; then # Attempt to use Python 2.7, if installed: DEFAULT_PYTHON="python2.7" else DEFAULT_PYTHON="python" fi ``` to just ```DEFAULT_PYTHON="python"``` I'm not sure if it is a great assumption that python2.7 is used by default, when python points to something else. ## How was this patch tested? (Please explain how this patch was tested. E.g. unit tests, integration tests, manual tests) (If this patch involves UI changes, please attach a screenshot; otherwise, remove this) Author: MechCoder <mks542@nyu.edu> Closes #14016 from MechCoder/followup.
