Quoting a Python function in order to apply it later

Given an object Foo, which has a set of methods Bar, Baz, Quux, and Close.

I want to wrap calls into Foo as follows

def 开发者_如何学JAVAwrapper(method_symbol, *args):
   object = Foo()
   apply(object.method_symbol, args)
   object.Close()

So later on, I can call wrapper(Bar, MySweetArgs) and have wrapper correctly dispatch.

Obviously in Lisp this would be simple, simply QUOTE method_symbol and away you go.

The goal is to properly allocate/deallocate resources in a text-efficient fashion. I would prefer not wrap all of Foo with a SafeFoo class.

If you want to call the method by its name, the wrapper function could look like this:

def wrapper(method_symbol, *args):
   obj = Foo()
   getattr(obj, method_symbol)(*args)
   obj.Close()

wrapper('Bar', 1, 2, 3)

You could also use the method directly, instead of its name:

def wrapper(method, *args):
   obj = Foo()
   method(obj, *args)
   obj.Close()

wrapper(Foo.Bar, 1, 2, 3)

If method_symbol is the string name then:

Foo.__dict__[method_symbol](*args)

would probably do it.
