paul j3 added the comment:
For documentation, ['this','is','a','test'] might be a bit clearer than 'this
is a test'.split(). But generating a list of strings by split is, I think, a
pretty basic idiom.
But for testing purposes the split() version is a bit more robust because it is
closer to what might appear in sys.argv.
In [196]: ['this','is','a','test'][-1] is 'test'
Out[196]: True
In [198]: 'this is a test'.split()[-1] is 'test'
Out[198]: False
That is, the 'id' of a string generated by a split is not the same as that of
an explicit string. sys.argv is created by a split in the shell and/or the
interpreter, so it too will fail this 'is' test.
