+    This option compiles Python without advanced optimizations, resulting in a cleaner and faster build process. By using `--prefix=/usr/local/python2.7`, you ensure the Python 2.7 executable is         installed as `/usr/local/python2.7/bin/python`. This can avoid overwriting or conflicting with files belonging to the system's default Python 3 installation, potentially breaking system utilities that rely on Python 3.
