Takes Exactly 2 Arguments (1 Given) When Including Self

Everytime I call my function def hello(self,value) I get an error : takes exactly 2 arguments (1 given) so what could I do ? Or is there another possibility to do this: self.statu

Solution 1:

It sounds like you aren't calling your hello function correctly. Given the following class definition:

classWidget(object):
    defhello(self, value):
        print("hello: " + str(value))

You are probably calling it like a static function like this:

Widget.hello(10)

Which means no instance of a widget class gets passed as a first param. You need to either set up the hello function to be static:

classWidget(object):
    @staticmethoddefhello(value):
        print("hello: " + str(value))

Widget.hello(10)

or call it on a specific object like this:

widget = Widget()
widget.hello(10)

Solution 2:

This is most probably because your hello function is not a class member. In that case you need not provide self in the method declaration....i.e. instead of hello(self,value) just say hello(value)

For example...this snippet works absolutely fine

defhello(value):
    print'Say Hello to ' + value

hello('him')

If this is not the case then please provide your code snippet to help you further.
