Partial function application (or "currying") is the act of taking a function with two or more parameters, and applying some of the arguments in order to make a new function. The "hello world" example for this seems to be this:
Let's say you have a function called `add`, that takes two parameters: >>> def add(left, right): ... return left + right Now let's say you want a function that always adds 2 to a number you give it. You can use partial function application to do this: >>> from functools import partial >>> add2 = partial(add, right=2) Now, you have a new function, `add2`, that takes one parameter: >>> add2(4) 6 --- Paul Woolcock pwool...@gmail.com On Mon, Jul 18, 2011 at 6:13 AM, Kurian Thayil <kurianmtha...@gmail.com> wrote: > > Hi, > > I am a newbie in python and would like to learn GUI programming.
