Hello!
I'm fooling around with a class wich can map cgi-parameters to
function named parameter.
I have a dic like
dic = {
'action': 'myfunc',
'x': 1,
'y': 2,
'z': 3
}
and I have a method
def myfunc(x, y, z, a=None, b=None)
What I want to do ist calling the method defined in 'action' with
all the named parameter, also instead of
self.myfunct(x= 1, y=2, z=3)
I want to do
f = getattr(self, dic['action'])
f(named parameter from the dic)
Its a little like zope does it, but i didnt find it in the Zope Sources ;-)
How can do that?
Thanks, AXEL. 2 1546

I assume you forgot the self parameter. What I want to do ist calling the method defined in 'action' with all the named parameter, also instead of self.myfunct(x= 1, y=2, z=3) I want to do f = getattr(self, dic['action']) f(named parameter from the dic) class A:
.... def first(self, x, y, z, a=None, b=None):
.... print "calling first"
.... print "x =", x
.... print "a =", a
.... a = A() d = dict(action="fi rst", x=1, y=2, z=3) d
{'y': 2, 'x': 1, 'z': 3, 'action': 'first'}
# as a sideeffect, pop() removes "action" from the dictionary
# make a copy if that bothers you bm = getattr(a, d.pop("action") ) bm(**d)
calling first
x = 1
a = None d["a"] = 99 bm(**d)
calling first
x = 1
a = 99

Thanks, that was exaclty what I needed, works cool now!

Hi,
First off I know that in almost all cases this would be a terrible thing to
do, but this is an unusual case where this makes sense.
Basically I have a procedure where you pass a string containting a template
for a tuple, the function then finds a tuple that matches this template and
then returns it. The template may contain variable names, which match
against anything in that position in the tuple - this is all working fine,...

First let me say please see the wiki page about python decorators if you

I propose (and others have) that built-in features have keyword support,
like static and class methods. Also, I believe it is more readable if
decorators, especially longer ones, are moved to the top of the function
body, just like docstrings, instead of coming before the function is

Suite-Based Keyword Arguments

Passing complicated arguments to functions is currently awkward in Python.
For example, the typical way to define a class property winds up polluting

Hello everyone,
I'm trying to do something in C calling Python and its failing. I'd be

What I'm trying to do is determine the address of the "collect" function

Hi All,
I've been working on a domain parking project where we need to analyze
a domain name, say "bookhotel", and get keywords(book, hotel) out of
it, then use these keywords to do some search.
There are two ways to do this as far as I can see, longest match and
quickest match.
Longest match:
bookhotel -check with a dictionary -False
