Rudimentary Currying and Partial Application in Python
- jmillikin 17y agohttp://docs.python.org/library/functools.html#functools.partial http://docs.python.org/library/functools.html#functools.part... This already exists in the standard library as functools.partial, except the stdlib version is better in nearly every way.
- ighost 17y agoI agree, but this "rudimentary" version is easier to understand for someone new to functional programming. It trades generality for pedagogical clarity.
- brutimus 17y agoThe one place where the functools.partial failed me was in partialing on class methods. functools.partial actually gives you a callable class, instead of the functional closure that this example gives you (though I don't really consider this to be that great of an example). When a class is instantiated, the method functions (unbound methods) are turned into bound methods, something a class can't be. Guido talks about this a bit whole process here... http://python-history.blogspot.com/2009/02/first-class-everything.html http://python-history.blogspot.com/2009/02/first-class-every...
- ighost 17y agoSo python guys are still looking for the One True Way to do this? How unpythonic.
