问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 5 years ago . If I defined a method: def weird_method(first_argument, second_argument) #code here end so this way I can pass arguments like : 1, :digit, 'some', "more"(Fixnum, Symbol, String etc.) , BUT what If I wanted to pass just this: argument1, argument2 , I mean values that have no type and look like local

问题 In my CakePHP App I'd like to pass arguments in a custom route. What works now (domain/controller/action/param) domain.com/dealers/view/1 What I'd like to do (domain/param/controller/action/param) domain.com/washington/dealers/view/1 This is my code in routes.php: Router::connect('/:city/dealers/view/:id', array('controller' => 'dealers', 'action' => 'view'), array( 'pass' => array('city', 'id') ), array('city' => '[a-z]+') ); This just redirects domain.com/washington/dealers/view/1 to domain

问题 in Python : may be so obvious, :) anyway, we are looking for ? , below: def printname(x): print ?,x >>> a = 1.3 >>> printname(a) >>> 'a',1.3 so something instead of ? to represent the name of passed argument. if not that obvious ? any trick or solution? 回答1: It's not impossible . You need to traverse back up stack frames and find the line of code that calls the function. It's an ok hack to do for debugging, but no way I would use it in real code Here's a starting point for you: import inspect

问题 I have the following PHP function: function func_name($name = 'John', $country = 'USA') { do something; } And now, am trying to pass variable to the function as follows: func_name($name = 'Jack', $country = 'Brazil'); I know, we can pass it easily as func_name('jack', 'Brazil'); but the above function is just an example. The actual function has around 20 arguments and all have default values, and some are not at all passed to the function So I would like to know if its proper to pass

问题 [ Original title referred to 'sizeof function'. ] I tried these and they all worked: char *p; printf("Size of *p is %d\n",sizeof(*p)); //result =1 printf("Size of p is %d\n",sizeof( p)); //result =4 printf("Size of p is %d\n",sizeof(&p)); //result =4 I wonder why the first printf is 1, the 2nd and 3rd is 4? So what arguments can sizeof can actually take? 回答1: It takes a type. sizeof(char) is always one. The variable p itself is a pointer, and on your platform that has a size of 4. Then you do

问题 I've tested the following code: function aa(...aArgs):void { trace("aa:", aArgs.length); bb(aArgs); } function bb(...bArgs):void { trace("bb:", bArgs.length); } aa(); //calling aa without any arguments. The output is: aa: 0 //this is expected. bb: 1 //this is not! When I pass empty arguments (aArgs) to bb function; shouldn't it return 0 length? Seems like function bb is treating the passed aArgs as non-empty / non-null.. What am I missing here? Any help is appreciated. regards.. 回答1: It looks

问题 I'm trying to learn how to pass an argument to setTimeout in a javacript for loop. Here is the example code. As it is currently written, setTimeout is passed the same exact i each time, not reflecting the different i's that are actually in the array. var a=100; for (i in array) { setTimeout("do_stuff(i, a)"), 2000); } (I've seen somewhat similar questions and answers here, but the code examples are much more complicated. Answering this most basic example could much help others with the same

问题 I'm not sure if I labelled my question correct, but I give it a shot: I want to use a package with a function which uses an ellipsis, func(...) . All my arguments of class My_Class are in a list. As I have quite a lot of arguments, I'd like to avoid func(arg1, arg2, arg3) . So ideally I'd like to do func( my_list ) . The problem is that the function looks like this function(...) { cl <- match.call(expand.dots = FALSE) names <- lapply(cl[[2]],as.character) ev <- parent.frame() classes <-
