Lisp's apply and funcall vs Python's apply

Lisp's APPLY is for calling functions with computed argument stored in lists.(Modified from Rainer's comment)

For example, the following code changes (list 1 2 3) to (+ 1 2 3).

(apply #'+ '(1 2 3)) 

However, Python's apply does what Lisp's funcall does, except for some minor differences (input is given as tuple/list)

(defun add (x y) (+ x y))
(funcall #'add 1 2) 
or
(func开发者_JAVA技巧all #'(lambda (x y) (+ x y)) 10 2)

apply(lambda x,y : x+y, [1,2])

What do you think? Are there more differences between Lisp's funcall and Python's apply?

Is there any reason why Python chose the name apply not funcall?

Because it's Python, not LISP. No need to have the same name, funcall is a LISP command and apply is something different in Python.

apply is deprecated in Python, use the extended call syntax.

Old syntax:

apply(foo, args, kwargs)

New syntax:

foo(*args, **kwargs)

In Common Lisp (funcall #'fun 1 (list 2 3 4)) is exactly the same as (fun 1 (list 2 3 4)), whereas (apply #'fun 1 (list 2 3 4)) would mean different things depending on the arity of fun.

* (defun bleargh (a &rest b) (cons a b))

BLEARGH
* (funcall #'bleargh 1 (list 1 2 3))

(1 (1 2 3))
* (apply  #'bleargh 1 (list 1 2 3))

(1 1 2 3)

So FUNCALL and APPLY do very different things, as it were.

Just a note:

Deprecated since version 2.3: Use the extended call syntax with *args and **keywords instead.

removed in py3k.

I don't see why you claim Lisp's apply() would do anything different than Python's. Both functions take a function and a list and then call the function with the list elements as arguments. ((+ 1 2 3) is an call to + with arguments 1, 2 and 3, isn't it?) To me it looks like both applys do exactly the same thing.

funcall on the other hand tales a function and several separate arguments (not a list containing arguments) and applies the function to these arguments.

Both Lisp's and Python's apply function do the same thing -- given a function f and a list of parameters p, apply f to p. The only difference is that Python's apply also accepts a dictionary for keyword arguments. In Lisp, these would be included in the parameter list as :keyword arguments.
