I actually wrote the book _ Functional Programming in Python_, yet I haven't the foggiest idea how to parse that code. A decorator parameterized buy two instances of the decorator function itself?! I know I could read the implementation and figure out why that works. But I don't want to encourage that code in real use. On Sep 20, 2016 11:17 AM, "Stephan Houben" <stephanh42@gmail.com> wrote:
I must admit I am a bit partial to partial, you can do fun things like this:
from functools import partial @partial(partial, partial) ... def add(x, y): ... return x+y ... add(3)(4) 7
I suppose that isn't exactly going to convince Guide to put it in builtins, though.

I find myself "partializing" in ways partial() doesn't support more often than not. E.g.
lambda first, third: myfunc(first, 42, third)
I think it's good to have partial() in functools, but it's two orders of magnitude less common than things that should be in builtins.

lambda *args, **kw: myfunc(partial_arg, *args, **kw)
which isn't more readable than just:
partial(myfunc, partial_func)
