Hi, I want to give a tuple to a function where the function expects the respective tuple-size number of arguments.
The following session illustrates what I want to do and the respective failure. Python 2.4.1 (#7, Aug 3 2005, 14:55:58) [GCC 3.3.1 (SuSE Linux)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> def foo(a, b): print a, b ... >>> t = (1, 2) >>> def foo(a, b): print 'a == %s, b == %s' % (str(a), str(b)) ... >>> foo(1, 2) a == 1, b == 2 >>> foo(t) Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: foo() takes exactly 2 arguments (1 given) >>> One way to do what I want is--of course--to call foo(t[0], t[1]). My actual question is if there is a smarter way to do it. The situation for me is that I take the functions from a library that I cannot modify. On the other side in my code I use the tuples.
