Not always.  Depends on context, partly subjective.

Comprehensions came along later and there was some noise made about
eliminating map for a while, though I think that's died down.

You could look at the functools module too, particularly
functools.partial.  For that matter, you could also try Haskell.  It's
even more concise, and this flavor of code is easier to keep reliable
when there's compile-time type checking.
