得到一个类型错误，不需要争论，请任何人帮忙解决这个问题

问题描述

class Student:
 def checkpassfail(self):
    if self.marks>30:
        return True
    else:
        return False

def __init__(self,names,marks):
       self.names=names
       self.marks=marks

student1= Student('jack',87)
print(student1.names)
print(student1.marks)

解决方法

这里在student类中，构造函数应该是这样定义的

class Student:
    def __init__(self,names,marks):
         self.names=names 
         self.marks=marks
    def checkpassfail(self):
        if self.marks>30:
            return True
        else:
            return False

student1= Student('jack',87) 
if student1.checkpassfail():
    print(student1.names)
    print(student1.marks)
