Re: [Python-Dev] Partial function application 'from the right'

Hello, Ben North <ben <at> redfrontdoor.org> writes:

I find 'functools.partial' useful, but occasionally I'm unable to use it because it lacks a 'from the right' version. E.g., to create a function which splits a string on commas, you can't say

# Won't work when called: split_comma = partial(str.split, sep = ',')

In py3k, we could also use "..." (the Ellipsis object) to denote places where an argument is missing, so that: split_comma = partial(str.split, ..., ',') would do what you want. Regards Antoine.
