Why do I get this error?
super().display() RuntimeError: super(): no arguments
I tried to call the display function from class Project
in Progress.display()
how to display the user's input? Here's the code:
class Project:
def __init__(self, name="", job="", **kwargs):
super().__init__(**kwargs)
self.name = name
self.job = job
def display():
print("name: ", (self.name))
print("job: ", (self.job))
@staticmethod
def prompt_init():
return dict(name=input("name: "), job=input("job: "))
class Stages(Project):
def __init__(self, stages="", **kwargs):
super().__init__(**kwargs)
self.stages = stages
def display(self):
super().display()
print("stages: ", (self.stages))
@staticmethod
def prompt_init():
parent_init = Project.prompt_init()
choice = None
while choice not in (1, 2, 3, 4, 5, 6):
print("Insert your stage now: ")
print("1. Planning")
print("2. Analysis")
print("3. Design")
print("4. Implementation")
print("5. Testing")
print("6. Release")
choice = input("enter your choice: ")
choice = int(choice)
if choice == 1:
stages = "Planning"
elif choice == 2:
stages = "Analysis"
elif choice == 3:
stages = "Design"
elif choice == 4:
stages = "Implementation"
elif choice == 5:
stages = "Testing"
elif choice == 6:
stages = "Release"
else:
print("no such input, please try again")
print(name)
print(stages)
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()
choice = None
while choice not in (1, 2, 3, 4):
print("1. 25%")
print("2. 50%")
print("3. 75%")
print("4. 100%")
choice = input("enter your choice[1-4]: ")
choice = int(choice)
if choice == 1:
progress = "25%"
elif choice == 2:
progress = "50%"
elif choice == 3:
progress = "75%"
elif choice == 4:
progress = "100%"
else:
print("no such input, please try again")
print(progress)
parent_init.update({"progress": progress})
return parent_init
class A(Stages, Progress):
def prompt_init():
init = Stages.prompt_init()
init.update(Progress.prompt_init())
return init

class New:

def add_project_test(self, name, job, stages):

def __init__(self):

print()
def add_progress(self):

self.project_list.append(Progress(**init_args))
def add_project(self):

Every time you use super() in a method, you need to be in an instance method or a class method. Your staticmethod
s 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()
