如何将员工添加到经理的主管？ （Python类）

Question

我有一个带有Manager类的Employee类，每个创建的员工都将获得Employee类的属性，甚至是Manager。

我的问题是，我想创建一个输入选项，要求经理输入他想要添加到其监督中的员工（将其添加到其员工列表中），并且还将添加员工属性（I知道最后3条线是有问题的，我只是无法弄明白）。

class Employee:

        def __init__(self,first,last,pay):    
                self.first = first
                self.last = last
                self.pay = pay
                self.email = first+'.'+last+'@company.com'

        def fullname(self):
                return '{} {}'.format(self.first,self.last)

class Manager(Employee): 

        def __init__(self,first,last,pay,employees=None):
                super().__init__(first,last,pay)
                if employees is None:
                    self.employees = []
                else:
                    self.employees = employees

        def add_emps(self,emp):
                if emp not in self.employees:
                    self.employees.append(emp)
                else:
                    print('the employee is already in your supervise')

        def print_emps(self):
                for em in self.employees:
                    print('-->',em.fullname())

emp_1 = Employee('Mohamad','Ibrahim',90000)

emp_2 = Employee('Bilal','Tanbouzeh',110000)

emp_3 = Employee('Ghalia','Awick',190000)

emp_4 = Employee('Khaled','Sayadi',80000)

mngr_1 = Manager('Ibrahim','othman',200000,[emp_1,emp_2])

mngr_2 = Manager('Rayan','Mina',200000,[emp_3,emp_4])

add_them = input('enter the employee you would like to add')

mngr_1.add_emps(add_them)

mngr_1.print_emps()

如果你不熟悉字典，我会给你一个快速的故事，但你应该阅读PyDocs，以及关于Hash Tables的一般维基百科条目。

a = {} # create an empty dictionary
a['some_key'] = "Some value" # Equivalent of creating it as a = {'some_key': "Some value"}
# Dictionaries are stored in "key, value pairs" that means one key has one value.
# To access the value for a key, we just have to call it
print(a['some_key'])
# What if we want to print all values and keys?
for key in a.keys():
    print("Key: " + key + ", Value: " + str(a[key]))

现在回答你的实际问题。我构建了一份员工字典，并从字典中将员工的密钥添加到了经理。我还展示了构建字典的两种方法：一种是在创建dict时添加值，另一种是在以后添加值。

class Employee:

        def __init__(self,first,last,pay):
                self.first = first
                self.last = last
                self.pay = pay
                self.email = first+'.'+last+'@company.com'

        def fullname(self):
                return '{} {}'.format(self.first,self.last)

class Manager(Employee):

        def __init__(self,first,last,pay,employees=None):
                super().__init__(first,last,pay)
                if employees is None:
                    self.employees = []
                else:
                    self.employees = employees

        def add_emps(self,emp):
                if emp not in self.employees:
                    self.employees.append(emp)
                else:
                    print('the employee is already in your supervise')

        def print_emps(self):
                for em in self.employees:
                    print('-->',em.fullname())


employee_dict = {
    'Mohamad_Ibrahim': Employee('Mohamad','Ibrahim',90000),
    'Bilal_Tanbouzeh': Employee('Bilal','Tanbouzeh',110000)
}
employee_dict['Ghalia_Awick'] = Employee('Ghalia','Awick',190000)
employee_dict['Khaled_Sayadi'] = Employee('Khaled','Sayadi',80000)

mngr_1 = Manager('Ibrahim','othman',200000,[employee_dict['Mohamad_Ibrahim'],employee_dict['Bilal_Tanbouzeh']])
mngr_2 = Manager('Rayan','Mina',200000,[employee_dict['Ghalia_Awick'],employee_dict['Khaled_Sayadi']])

add_them = input('enter the employee you would like to add') # Expects the name like the keys are Firstname_Lastname

mngr_1.add_emps(employee_dict[add_them])

mngr_1.print_emps()
