python 3 error RuntimeError: super(): no arguments

Not 100% solution to the answer, but same error. Posted with love for Googlers who have the same issue as me.

Using Python 3, I got this error because I forgot to include self in the method. Simple thing, but sometimes the most simple things trip you up when you're tired.

class foo(object):
    def bar(*args):
        super().bar(*args)

=> RuntimeError: super(): no arguments

Remember to include your self

class foo(object):
    def bar(self, *args):
        super().bar(*args)

Every time you use super() in a method, you need to be in an instance method or a class method. Your staticmethods don't know what their superclasses are. Observe:

class Funky:
    def groove(self):
        print("Smooth")

    @staticmethod
    def fail():
        print("Ouch!")

    @classmethod
    def wail(cls):
        print("Whee!")


class Donkey(Funky):
    def groove(self):
        print(super())

    @staticmethod
    def fail():
        try:
            print(super())
        except RuntimeError as e:
            print("Oh no! There was a problem with super!")
            print(e)

    @classmethod
    def wail(cls):
        print(super())


a_donkey = Donkey()
a_donkey.groove()
a_donkey.fail()
a_donkey.wail()

Outputs:

<super: <class 'Donkey'>, <Donkey object>>
Oh no! There was a problem with super!
super(): no arguments
<super: <class 'Donkey'>, <Donkey object>>

Here's your code, debugged and with some extra functionality and tests:

class Project:
    def __init__(self, name="", job="", **kwargs):
        super().__init__(**kwargs)
        self.name = name
        self.job = job

    def display(self):
        print("name: ", self.name)
        print("job: ", self.job)

    @staticmethod
    def prompt_init():
        return dict(name=input("name: "), job=input("job: "))


class Progress(Project):
    def __init__(self, progress="", **kwargs):
        super().__init__(**kwargs)
        self.progress = progress

    def display(self):
        super().display()
        print("progress: ", self.progress)

    @staticmethod
    def prompt_init():
        parent_init = Project.prompt_init()
        progress = input("your progress: ")
        parent_init.update({
            "progress": progress
        })
        return parent_init


class New:
    def __init__(self):
        self.project_list = []

    def display_project(self):
        for project in self.project_list:
            project.display()
            print()

    def add_project(self):
        init_args = Project.prompt_init()
        self.project_list.append(Project(**init_args))

    def add_progress(self):
        init_args = Progress.prompt_init()
        self.project_list.append(Progress(**init_args))


my_list = New()
my_list.add_project()
my_list.add_progress()
my_list.display_project()
