所以我的代码可以正常工作，但是有两行代码让我感到困惑，而且不太确定该放什么。
代码(标出两行):
class Person(object):
numPerson = 0
def __init__(self,firstName,lastName):
self.firstName = firstName
self.lastName = lastName
def fullName(self):
print self.firstName +' '+self.lastName
class Employee(Person):
numEmployee = 0
def __init__(self,firstName,lastName,pay,employID):
Person.__init__(self, firstName, lastName)
self.pay = pay
self.employID = employID
Employee.numEmployee += 1
class Programmer(Employee):
def __init__(self,firstName,lastName,pay,employID,proLang):
self.proLang = proLang
Employee.__init__(self, firstName, lastName, pay, employID)
class Manager(Employee):
def __init__(self,firstName,lastName,pay,employID,progList):
self.progList = progList
Employee.__init__(self, firstName, lastName, pay, employID)
def addProgrammer(self):
self.progList.append(Programmer.fullName) <------------------- This line
def removeProgrammer(self):
if len(self.progList) == 0:
pass
else:
del self.progList[0]
def printList(self):
print self.progList
a = Manager('Alfred','Jones',20.00,0001,[])
b = Programmer('James','Smith', 11.75, 0002, 'Java')
a.addProgrammer() <--------------------------------------------- And This line
a.printList()
我正在尝试将程序员的名字添加到 progList使用 .addProgramer方法。我一直在尝试不同的组合，这是我得到的最接近的组合。
输出:
[<unbound method Programmer.fullName>]
所以，我不确定 addProgramer 中需要包含什么方法以便正确添加程序员姓名，或者如果我需要在 a.addProgrammer 中添加参数在最后。
请您参考如下方法:
这里:
self.progList.append(Programmer.fullName)
您不是在添加程序员的实例，而是在添加来自程序员类的方法。
还有:
def fullName(self):
print self.firstName +' '+self.lastName
这实际上并没有返回程序员的姓名，它只是将其打印到控制台。要实际输出和使用全名，您需要 return self.firstName + ' ' + self.lastName
同样在该函数中，您还需要指定要添加的程序员:
def addProgrammer(self, added_programmer):
self.progList.append(added_programmer.fullName()) # Call the function to get the fullname
现在添加一个程序员:
Alfred = Manager('Alfred','Jones',20.00,0001,[]) #make a manager
James = Programmer('James','Smith', 11.75, 0002, 'Java') #make a programmer
Alfred.addProgrammer(James) #add the programmer
Alfred.printList()
把这些放在一起:
class Person(object):
numPerson = 0
def __init__(self,firstName,lastName):
self.firstName = firstName
self.lastName = lastName
def fullName(self):
return self.firstName +' '+self.lastName
class Employee(Person):
numEmployee = 0
def __init__(self,firstName,lastName,pay,employID):
Person.__init__(self, firstName, lastName)
self.pay = pay
self.employID = employID
Employee.numEmployee += 1
class Programmer(Employee):
def __init__(self,firstName,lastName,pay,employID,proLang):
self.proLang = proLang
Employee.__init__(self, firstName, lastName, pay, employID)
class Manager(Employee):
def __init__(self,firstName,lastName,pay,employID,progList):
self.progList = progList
Employee.__init__(self, firstName, lastName, pay, employID)
def addProgrammer(self, added_programmer):
self.progList.append(added_programmer.fullName()) # Call the function to get the fullname
def removeProgrammer(self):
if len(self.progList) == 0:
pass
else:
del self.progList[0]
def printList(self):
print self.progList
Alfred = Manager('Alfred','Jones',20.00,1,[])
James = Programmer('James','Smith', 11.75, 2, 'Java')
Alfred.addProgrammer(James)
Alfred.printList()
