This is one line of Python code alright, but it's not a "one-liner" in
the "computes the a normalized vector"-sense (which was the original
challenge, if there ever was one).
If anything, you are now ready to compute the *norm* of a vector in a
subseqent line. (Or, if you must, after a semicolon on the same line.)
