According to PEP 394 recommendation [1], it's more portable to use python2 rather than plain python to refer python binary version 2.
Since there're distros using python3 by default like Arch, and we don't support python3 (yet), it'd be better using python2 explicitly. But older versions (prior to 2.7) seem not to provide python2 but just python. Given that it's only old version, try python2 first and then fallback to python. It'll ensure that it always points to python 2.x.
