I had a work mate make this exact same point literally yesterday. He asked me if Python had an identity function, and when I suggested just using `lambda x: x` he grouched that this wasn't sufficiently obvious enough as "identity" is self-explanatory.
(Perhaps for English speakers with a background in mathematics or functional programming.)
I'm not really convinced. Its easier to just write a lambda than to `from functools import identity`, and despite what my workmate thinks, "identity" is not self-evident. Consider that identity could also be a function that returns a person's identifying information. Think about the English usage of "identity theft" and "secret identity", rather than the mathematical meaning.
So I'm at best +0 on this suggestion. |
