NameError on imported class

Question

如何摆脱这个NameError？

main.py

from com.domain.model import Employee 

e1 = Employee("") 

---

model.py

class Person(object): 
    def __init__(self,fname): 
     setfname(fname) 
    def setfname(fname): self._fname = fname 

class Employee(Person): 
    def __init__(self,fname): super(Employee,self).__init__(fname) 

---

NameError: global name 'setfname' is not defined

---

main.py

com/

- domain/

---- model.py

Answer 1

资格setfname为self.setfname。除此之外，实例方法setfname应该具有self作为第一个参数。

class Person(object): 
    def __init__(self, fname): 
     self.setfname(fname) 
    # ^^^^^ 
    def setfname(self, fname): 
    #   ^^^^^^ 
     self._fname = fname
