arguments

问题 Here is what I have- A CGI script on server A gets the parameters entered in a webform, creates a remote ssh command that calls another perl file on server B and passes all parameters as arguments to the ash command. Perl file on server B parses arguments n operates thereafter. Now since I won't have all parameters populated at all times, I am passing a character such as "=" appended to each parameter from CGI on server A and before processing on Server B, I chop that last character which is

问题 i am writing a jquery lib and i need to implement Datetime functions. i need to create a .Date() function which return a new Date object. How to pass arguments of my .Date(args) function to Date object constructor so to create a new date object? i tried something like this, me is the plugin namespace, me=$.jqGUI. //.Date(Value) /* Return a date object. * ReturnValue = Date(Value) */ me.Date = function(Value){ //pass arguments to Date constructor var sDate = Date.prototype.constructor.apply

问题 I often find myself writing class constructors like this: class foo: def __init__(self, arg1, arg2, arg3): self.arg1 = arg1 self.arg2 = arg2 self.arg3 = arg3 This can obviously become a pain if the number of arguments (and class attributes) gets high. I'm looking for the most pythonic way to loop through the constructor's arguments list and assign attributes accordingly. I'm working with Python 2.7, so ideally I'm looking for help with that version. 回答1: The most Pythonic way is what you've

问题 I have been using HTML Parser to scrapping data from websites and stripping html coding whilst doing so. I'm aware of various modules such as Beautiful Soup, but decided to go down the path of not depending on "outside" modules. There is a code code supplied by Eloff: Strip HTML from strings in Python from HTMLParser import HTMLParser class MLStripper(HTMLParser): def __init__(self): self.reset() self.fed = [] def handle_data(self, d): self.fed.append(d) def get_data(self): return ''.join

问题 I created bool dropIndexes to void ladujZBazy and created if (dropIndexes) beacuse When I checked items on list in checkedListBox1 and search some items using textBox1 my previous check is gone. I have some problem with no argument was given for the "dropIndexes" formal parameter of the "dbopakowania.ladujZBazy (string, bool)". namespace Email_Sender { public partial class dbopakowania : Form { EmailSender emailsender; public List<List<string>> listOpakowaniaTabela = new List<List<string>>();

问题 I have a script that reads a variable number of fields from an input file and pass them to a function as arguments. For example: file 1 with fields: A,B and C => function(A,B,C) file N with fields: A,B,C and D => function(A,B,C,D) My question is: How to feed the function with the right number of fields accordingly to the input file?. PD: Of course the function accepts any number of arguments 回答1: Read the fields (arguments) into a list and then use argument unpacking: function(*fields) Below

问题 I have defined this function def writeonfiles(a,seed): random.seed(seed) f = open(a, "w+") for i in range(0,10): j = random.randint(0,10) #print j f.write(j) f.close() Where a is a string containing the path of the file and seed is an integer seed. I want to parallelize a simple program in such a way that each core takes one of the available paths that I give in, seeds its random generator and write some random numbers on that files, so, for example, if I pass the vector vector = [Test/file1

问题 So today I figured (for the first time admittedly) that int foo() is in fact different from int foo(void) in that the first one allows any number of inputs and the second one allows zero . Does int foo() simply ignore any given inputs? If so, what's the point of allowing this form of function? If not, how can you access them and how is this different from having a variable argument list (e.g. something like int foo (int argc, ...) )? 回答1: The key to understanding this is understanding the

问题 I'm looking for something that works like Lisp's arg-supplied-p variables, to help differentiate a default value from the same value specified by a user. Example: def foo(a=10): pass I'd like to know in foo if it was called like this: foo() or like this: foo(10) or even like this: foo(a=10) The last 2 are synonymous enough to me; I don't need to know that detail. I've looked through the inspect module a bit, but getargspec returns exactly the same results for all 3 calls. 回答1: Except for
