Pythonのクラスの印刷情報発行

Gokberk：

私は自分で基本的なクラスの例を作成しようとしました。しかし、私は次のコードに#ERRORが言及したことを51行からのエラーを取得します。エラー情報は以下の通り。私は労働者階級からshow_infoにより情報を取得しようとする場合も、プログラムにはエラーはありません。私はそのような状況のthaの理由を理解することができませんでした。

あなたはこの問題を解決する方法についての私を助けることができます。私はコーディングのためのbegginerよすべてに感謝します。申し訳ありませんが主な問題はとても基本的である場合。

class worker():

    def __init__(self, name, salary, department):
        print("__init__ function of worker class.")
        self.name = name
        self.salary = salary
        self.department = department

    def show_info_worker(self):
        print("show_info function of worker class")
        print("""Name: {}\nSalary: {}\nDepartment: {}""".format(self.name, self.salary, self.department))

    def change_depart(self, new_depart):
        print("change_depart function of worker class")
        self.department = new_depart



class manager(worker):

    def __init__(self, name, salary, department, responsibilty):
        # super() function takes input from worker class
        super().__init__(name, salary, department)
        print("__init function of manager class")
        self.responsibilty = responsibilty

    def show_info_manager(self):
        print("show_info function of manager class")
        return """Name: {}\nSalary: {}\nDepartment: {}\nResponsibility: {}""".format(self.name, self.salary,
                                                                                    self.department,
                                                                                    self.responsibilty)

    def raise_salary(self, increase_salary):
        print("raise_salary function of manager class")
        self.salary += increase_salary


employee_name = input("Please Enter Employee Name: ")
employee_salary = input("Please Enter Employee Salary: ")
employee_department = input("Please Enter Employee Department: ")
while True:
    check_manager = int(input("""Please Select the Position of Employee\n1. Worker\n2. Manager"""))
    if check_manager == 1:
        worker1 = worker(employee_name, employee_salary, employee_department)
        worker1.show_info_worker()
        break
    elif check_manager == 2:
        manager_responsibility = input("Please Enter Manager Responsibility: ")
        manager1 = manager(employee_name, employee_salary, employee_department, manager_responsibility)
        manager1 = manager.show_info_manager()  # <-- ERROR!!!
        break
    else:
        print("Please Enter a Proper Value...")

エラーは以下の通りです。

manager1 = manager.show_info_manager()
TypeError: show_info_manager() missing 1 required positional argument: 'self'

Saimon :

あなたは、私が修正し、あなたのコード内で何かを台無しに。あなたは、呼び出そうとしたshow_info_manager()上でmanager1間違った方法でインスタンスを。
