Error lling a variable from class method

[Maurice Waka]

Am working on a simple game/app. When I call a variable on web2py view, I get this error:

quack= duck.quack()
TypeError: unbound method quack() must be called with duck instance as first argument (got nothing instead)

my codes are here: In the module module

from gluon import *
class duck():
    def quack():
        return 'Quacks like a duck'
    def walk():
        return 'Walks like a person'

In the controller

def data_filters():
    fils = duck.quack()
    return dict(fils=fils) 

In the view:

{{extend 'layout.html'}}

{{=fils}}

[Leonel Câmara]

Try this in modules

class Duck():
    def quack(self):
        return 'Quacks like a duck'
    def walk(self):
        return 'Walks like a person'

Then in the controller

def data_filters():

    duck = Duck()
    fils = duck.quack()
    return dict(fils=fils)

Even better:

class Duck(object):

I noted that my methods were static and all i needed was to do this:

@staticmethod

def quack():

    code

This worked

Thanks anyway for the help
