# Python Symlink
|
|
|
|
Symlinks `python` to `python3` when Python 2.7 is not installed
|
|
|
|
## Overview
|
|
|
|
This script checks if `python3` is available and if `python` is not available. If both are true, then the script
|
|
symlinks `python` to `python3` so that the `python` command uses `python3`.
|
|
|
|
This is useful if you do not want to install Python 2.7 and would like Python 3 to be used in all scenarios where Python is
|
|
invoked with the `python` command.
|
|
