copied!<p>The code:</p> <pre><code>class Curried(object): def __init__(self, func, args=None, kwargs=None): self._func = func self._args = () if args is None else args[:] self._kwargs = {} if kwargs is None else dict(kwargs) self._name = None def __call__(self, *args, **kwargs): if args or kwargs: return Curried(self._func, self._args + args, dict(self._kwargs.items() + kwargs.items())) else: return self._func(*self._args, **self._kwargs) def __str__(self): if self._name is None: self._name = self._get_curried_name() return self._name def _get_curried_name(self): _args = ([str(a) for a in self._args] + ['{}={}'.format(k, v) for k, v in self._kwargs.iteritems()]) all_args = ", ".join(_args) return '<curried {}({}) at 0x{:x}>'.format( self._func.func_name, all_args, id(self)) def curry(func): _curried = Curried(func) return _curried </code></pre> <p>Test:</p> <pre><code>@curry def f(a, b, c, flag_foo=True, flag_bar=False): return 'horray!' print f print f(1, 2, flag_bar=True) print f(1, 2, flag_bar=True)(3, flag_foo=False) print f(1, 2, flag_bar=True)(3, flag_foo=False)() </code></pre> <p>And the result:</p> <pre><code><curried f() at 0x100484210> <curried f(1, 2, flag_bar=True) at 0x100484250> <curried f(1, 2, 3, flag_bar=True, flag_foo=False) at 0x100484310> horray! </code></pre> <p>Instead of a "pure" function, here you get a callable class that acts as a function. You evaluate the name only once. Of course, if you want <code>func_name</code> you can add such variable as <a href="http://docs.python.org/2/library/functions.html#property" rel="nofollow"><code>property</code></a> and return <code>str(self)</code> which is evaluated once</p>
