function factories and argument names


i know how to programmaticall y create python functions:
module = __import__( '__main__')
def factory( val ):
def f( arg=val ): print arg, val
f.__name__ = 'function%s' % x
return f

for x in [1,2,3,4]:
func = factory( x )
setattr( module, func.__name__, func)
but i'd like to add a little more customization: i'd like to vary the
name of the argument to the function, which is now fixed as 'arg':

help( function2 )

# Help on function function2 in module __main__:
#
# function2(arg=2 )

ideally i'd like to create each function in the example with the given
format:

function1(arg1= 1)
function2(arg2= 2)
function3(arg3= 3)
function4(arg4= 4)

i know that the function will behave the same regardless of the arg
name, but i would like to help convey to the user what the meaning of
the argumetns are. plus, i would also like to vary the number are
keyword args.

thanks in advance,
chad

Hello all, I am writing a script where I need to use the system() function to call htpasswd. I can do this just fine on the command line...works great (see attached file, test.php). When my webserver runs that part of the script (see attached file, snippet.php), though, it doesn't go through. I don't get an error message or anything...it just returns a "1" (whereas it should return a "0") as far as I can tell. I have read the PHP...

I'm wondering how Python cognoscenti use/implement factory patterns in Python. In my limited C++ experience, one reason to use a factory method is to make it easier to create instances of classes derived off a base class. The instance is declared to be an instance of the base class. The factory returns an instance of a derived class, and everything is groovy. In Python, since type declarations need not be static, it seems there is no...

I mean, it's very convenient when default parameters can be in any position, like def a_func(x = 2, y = 1, z): ... (that defaults must go last is really a C++ quirk which is needed for overload resolution, isn't it?) and when calling, just omit parameter when you want to use defaults: a_func(, , 3)

Suppose I have this function: def f(var=1): return var*2 What value do I have to pass to f() if I want it to evaluate var to 1? I know that f() will return 2, but what if I absolutely want to pass a value to f()? "None" doesn't seem to work.. Thanks in advance.

Hi, all. I have a Windows DLL that exports a number of functions. These functions expect to receive a pointer to a callback function and an opaque void* parameter. The callback functions are typedef'd to take void* parameters, through which the DLL's function passes its void* parameter to the callback function. This allows me to use class instances as callback handlers, as in the example below. //Executable and DLL know this:

In my opinion, C not mungling its function names imposes unnecessary complexity on C++, requiring extern 'C' { ... } everywhere in headers. I believe that in the next version of the ISO standard, C should move to mungling its function names consistently with C++ to improve interoperability. Acutally this should have happened long ago. Regards, Jim
